[@lisastonehouse6441]

Literally can't thank you enough. Years of slow file editing on big shoots thinking it was all down to memory.

[@dougdavidson9227]

Happy New Year Anthony! Watched your video and checked my porttable LcR hard drive and it is 5TB with all kinds of free space. I jumped the cache to 200 and SNAP. Speed beyond belief. Every functions snaps like I have never seen before. GREAT TIP and thank you.

[@51hcmiller]

Awesome advice, which brings up a nother question. Should we ever need to "clear the cash" ? Just a friendly suggestion, maby if you ever run out of ideas to share, how about a tutorial on the best way to set ALL the preferences.

[@ajk2749]

Dang! That's all I needed to do?! My SSD C drive has 260 GB free so I increased the cache from 25 GB to 100 GB. It flies now! What a difference! Thank you, Anthony!

[@kwilliams1810]

Thankyou so much, I was able to allocate 150gb and it is now rocketing along. In one collection that had over 3000 images, rendering in Library view was an absolute pain but now I cant keep with it. Its near instant - what an amazing tip!

[@davidward1224]

Great advise. I've also read that putting the cache onto a separate drive will help with performance.

[@J5388T]

Agreed, a separate drive to the OS helps greatly.

[@amywright2942]

THANK YOU!! This worked like a charm!😊

[@debbyzinha1000]

I have 2tb of space and is was at 30.0 🤦🏻‍♀️ just put it to 100 now and mask is working SO MUCH FASTER!! Thank you so much !

[@Raytrace3Dee]

Great Tip and it works, Initially :-) - Mine was set to 20GB after I saw this video a while back (Thanks) and eventually the slowness returned. I checked the cache folder and there were 48K (48 Thousand) cache files within. I think that results in LR constantly trying to manage them all. I closed LR and deleted them all. reopened and the speed is back. I would say this is a 2-parter and its OK to purge the cache when the need arises. LR just recreates the cache.dat and index.dat files. And Thanks again.

[@MrsBuniGu]

Thank you so much, I changed it to 20GB, and works great for me!!

[@thayerbigelow6436]

Thanks!

[@AnthonyMorganti]

Thank you Thayer!

[@lasticonoclast]

Just did this, and the change is amazing. I now won't need to wait on my M1 powered iMac to increase efficiency.

[@michaelt2961]

Thanks for this tip. I only have 8 gigs of ram and an old i7 laptop. I increased my 5 to 100. It sure made a difference.

[@niftytwo]

Thank you Anthony. I’ve been having problems with Lightroom Classic for over a week but I’m hanging in there. I will use your ideas. Stay safe.

[@oldtvnut]

Thanks! Seems like this eliminates the wait for full-res images to display.

[@leniehulse1621]

Happy New Year Anthony! Thanks for enlightening us!

[@NigelDesmond]

When deciding on a Cache size I set it for a large number, as you do in the Tutorial, and then start a normal editing session. As I proceed I monitor the size of the cache against performance once I have an idea of the cache I am using in normal usage patterns, I can set the minimum to something as a multiple of the expected actual eg. if I find I am using a cache of around 10GB then I would set the cache to 20 or 30GB, which gives a good amount of spare capacity. Obviously I monitor the cache usage occasionally especially if the image size being used changes - I have a bespoke SSD drive for editor catalogues and temp files Etc so keep the size smaller than the max available as other applications need room on the SSD used for Caches. This System has been my default in my 40+ years as an IT pro so is a proven way of working with temporary files.

[@SubiTrekker]

Thanks Anthony. Happy New Year!

[@bolt339]

Thanks for tutorial Anthony, i bumped up the figure, as you suggested & hey presto, Lightroom has almost doubled it's processing speed, thanks very much!

[@Kinadnuf]

Thank you and happy new year.

[@eavesphoto]

What Mac are you using Lightroom on? What operating system? What’s the processor and how much ram are you running Anthony?

[@Pomdaddy]

Once again Anthony You Rock!!!

[@geoffclinton8575]

Thanks for this "upgrade" Lightroom much faster.

[@gerrysladephotography7927]

Thanks Anthony, great tip!

[@jimhanner2091]

YES ,Thank You

[@pavelmuzykin4924]

thanks a lot it works perfectly.

[@barakeylam]

Thanks, It really worked!

[@BobG-eh5fc]

Thanks for another great tip, wonder if it gets reset after every update?

[@igorsharykin6020]

Thank you! 😀

[@yaeckerphotography]

Worked great with the loading of my 45 mp images. They took forever before this change 👍

[@pollypowell3907]

Question. I use a 5T portable hard drive. Does Lightroom process on the main hard drive and then just store the info on the file designated on the external drive? Bought the external this past year because the computer was filling up. Still learning the computer part of all this information. Thank you so much for your wonderful content. One of the first things I do with the morning coffee is see what you have posted.

[@roniamarie]

I also have this question

[@skymedia2119]

Omg this really helped! Thank you i actually thought about getting a whole new computer lol

[@johna.benigno4172]

Interesting, many thanks Anthony. Do you think the same "trick" would apply to Adobe Camera Raw in Photoshop? Many tanks.

[@seaned8]

This is amazing. Thank you.

[@JoshxIZ]

Thanks 🙏

[@timgimbert3073]

One of my big hassles was culling on the iPad but working and storing the files on my laptop. The laptop has been having problems syncing with the Smart Previews in the Adobe Cloud. I just changed this setting to 100GB and my laptop immediately started syncing with the cloud. I have gone to bed and it was syncing about 700 files at that stage. If this just makes syncing seamless I am ecstatic!

[@DrJoeJoeHands]

Thank you

[@brianwillert2833]

This also works in Photoshop thanks a million.

[@TomatenDK]

I have a brand new "gaming" pc with 32 gig ram and a 2070 rtx card. Runs like a beast with everything. But.... when Im in LR and grab a slider and start to move it, the picture that I edit starts to blink (a tiny super quick stutter) everytime I grab a slider. Its super frustrating ! Have googled the problem, but no answers. Do you have any idea what to do ? Reinstall LR maybe ? Its just......... aaaaargh - this shouldnt happen !!! :(

[@urbandefinition]

I’m in a similar boat. You expect Lightroom to just work if you have a high end system

[@TomatenDK]

@@urbandefinition i even have an 3070 rtx card. Not 2070 :) Yeah it seems like its my expensive gaming monitors fault. If I drag LR over to my secondary, OLD, BenQ monitor, its all fine. So annoying 😡

[@JensMHA]

Blast, that was fast! Much obliged. 😀

[@陳光昭-f6o]

Could you make a tutorial video to teach us how to make the title in the beginning of your video? Thanks a lot.

[@petergeernaert4696]

Happy New Year Anthony. Nice tip for LrC. I can't find the tab Lightroom Classic,De row begins with File, Edit, etc. I'm working with Windos.

[@hanswi336]

That's what he showed you in the video at 0:52 ......

[@joelbarto1103]

Does ACR have a similar setting? I've been getting some weird lag with my Wacom pen and the Brush tool in ACR.

[@thomasmccullaugh7002]

I only have the graphic processor setting in Performance. The other settings aren’t there. I have LR6. Am I doing something wrong?

[@allumpfa]

Happy New Year Anthony and thanks for this tip. Question if you are images are in one location such as an external drive does the cache have to be on the same drive or can it e.g. on your main hard disc drive?

[@bobcohen4008]

Thanks Anthony. On my Windows 10 system I found that my cache was already set at 100 MB but that it had a location on drive C: which is an SSD. I moved it to a rotating disk drive with plenty of available space and I'll see how performance changes.

[@gosman949]

you really want your cache on the faster SSD. I have a 512gb SSD devoted to my cashe. My LR is a blazing!

[@bobcohen4008]

@@gosman949 Thanks. I just moved it back to the SSD. Sometimes doing nothing is the best thing.

[@jpdj2715]

If you really want to optimize performance, then it goes a bit deeper. Your Windows PC's processor has a number of PCI express I/O lanes that depends on motherboard and processor. Generally, a higher end graphics card takes 16 of these lanes in a direct link with the CPU (there's nothing standing in the way between the processor and the GPU). Another 4 lanes from the processor go to what is generally called the "South Bridge" (SB) and all or most of your other I/O devices connect to that SB. Consequently, I/Os have their maximum speed limited by this "switch". If several I/O devices are used to I/O by the processor then these compete for time with the processor over the 4 lanes. That's given 1. Then there are the logical data streams in your PC where all executables (binary files) are read from your C: drive (operating system, applications), you may have your photos on the same (C:) drive, the operating system has its Page File there and Lightroom Classic has its cache on it. As C: can be throttled by other I/Os, each of these data streams can happen at the same time and compete for time on the 4 PCI express lanes. As I shoot a 46MP camera and the raw files are rather big, I ran into the limits of Windows 10 64 and hardware with a 16GB RAM, Core i7 9th gen, discrete NVIDIA GPU with 4GB video RAM and TB3 I/O. With LrC or CR working with two 4K displays that the notebook supports, working had become impossible. I rebuilt my old workstation with a 10th gen Core i7, 64GB of very fast RAM and an 11GB graphics adapter. LrC frequently drives W10-64 over the 32GB memory threshold and the 64GB are totally justified. Also, the graphics adapter sees its memory use run over 8GB frequently, making the 11GB justified. So, in this beast-station, I placed a RAID card and run an array of 4 SSD off of it in RAID 0 over their own "private" 4 PCI express lanes directly to the CPU without the SB in between. After I had finished robustness testing the workstation, I ran the SPECmark performance benchmark test and it scored 98th percentile in its class - at default settings, nothing overclocked. The RAID 0 array stores cache files and page file and catalogue files. Raw images and memory cards are on TB3 on their own PCIexpress links to the processor. So this takes lots of I/O-waits out of the picture (Task Manager). I have all edits in LrC stored in sidecar files with the raw images.

[@bobcohen4008]

@@jpdj2715 You're well beyond me in this area. I've got a camera with a 45.7 MP sensor, so I'm interested in optimizing LR and PS, but I recognize that my technical knowledge in this area is relatively limited. If it's something relatively simple like changing the size of the cache on the LR Performance page, I'll give it a try. I recognize my limitations! I'm not going to rebuild my computer anytime soon. But thank you for your instructive comments!

[@jpdj2715]

@@bobcohen4008 - appreciated, thanks for your reply. If your computer is a notebook, and it has Thunderbolt 3 connections, then you can use these TB3 connections to hook up storage devices that take care of parts of what I wrote, or else forget it. If you have a desktop/deskside PC that can have adapter cards, then you could try to find a diagram of the motherboard and its PCIe lanes the numb er of lanes is in the motherboard but it may be able to hold CPUs with different numbers of lanes, so there is something to figure out. It's not difficult, so far is it? Such a diagram, such diagrams, will reveal which I/O connectors on the motherboard dangle off the SB. Most M.2 connectors are on the SB and this explains why people are generally disappointed by the I/O performance of their very fast M.2 SSD. A PCIe RAID expansion card may cost as little as $40 and have 4 to 8 lanes. It may be a sort-of passive PCIe card that only converts PCIe motherboard lanes to I/O connectors and that's fine. It just means you define the RAID array in Windows (Disk Manager) instead of the BIOS/UEFI on the motherboard. Easier, and equally fast. What has the most impact? LrC relates its preview calculations to your horizontal display resolution and 2x 4K is 7680 - a lot of preview calculation work. Processing that can benefit a lot from a higher end video card with a lot of video RAM (a GTX is enough as LrC does not use an RTX card's ray-tracing to calculate your photos). When is faster I/O more beneficial to you? When you need to wait too long in your perception for a photo to load when you set LrC to show it to you. When I go to 200% or the next 46MP shot, I am not aware I have to wait for the image to build - it's "immediate". Exporting e.g. to JPEG is a lot of calculation and I/O, but, like importing, it is a batch job that you can start before going to bed, have a drink, instead of sitting there waiting for the Mudbricks to finish your job.

I tried you suggestion and LR seems to be a bit quicker. Thanks.

What if I have a lot of ram memory? (64 gb)

[@paulchoccyt1303]

I changed mine to 60gb like a year ago

[@TomatenDK]

I just found out why my picture flickers/stutters everytime I grab a slider in edit or even just click on the photo. Apparently its my big gaming monitor that causes it :O I dragged LR onto my secondary 15 year old BenQ monitor and now there it runs smooth. What the hell ! :O Must be the refresh rate or something. But yeah....turns out its the monitor. Oops :D

[@gosman949]

Anthony, just got a new Epson P-900 printer for the new year! With the rebate offered, they probably sold many this holiday season. Please make some printing videos for LR and PS please! There is nothing like a good honest hard print to finalize the photo process.!

[@mack689]

5gb cache = 10k of cached images in lightroom. 100gb =~200k images. where's the purpose? you can have 20gb cache and clear it after you're done with the project

[@exogendesign4582]

no matter what version Lightroom classic is clunky as fvck. The only worst Software ever that's close to being unusable by adobe, I had to manually upload to photoshop, since radial mask and brush sucks so bad. My machine is pretty new with top tier specs. I guest I should suck it out and learn capture one.

[@bruceneeka]

Might be good advice but it takes whole minute before you get to real stuff and then so much useless info on top of it. So to make lightroom faster I watched very slowly unfolding video that could have been about 15 seconds
