It would be great to have a video like this for TrueNAS. A lot of the SMB settings need to be input under auxiliary parameters so it's not obvious what to prioritize.

[@SpaceRexWill]

I have been meaning to and will have one in the future. The biggest issue that I have is the number of machines I have actually tuned. I setup 3-4 times a week so I have seen it all (almost) TrueNAS boxes end up being 1/20th of that.

Hi Will! Thank you for all your videos, they are AMAZINGLY helpful. One question I haven't see an answer to is do you set your Synology with a static local IP or do you let your router assign it whatever it gives it? I have always used a static, but I wanted to see what you suggest and why. Thank you!

[@MRForever-ub5pw]

Just got my Synology DS920+. When I transfer movies from my laptop (hardwired) to my old WD EX4100, I get a consistent 111-113 MB/s. When I try the same files going to the new 920+, it starts off at those levels and then drops all the way down to 20 MB/s at about the 30=40 percent complete mark. Then it goes up and down but rarely going above 90 MB/s. I made the adjustments you suggested (they did improve a little). I also swapped cat6 cable and changed switch port. I have one drive in the 920+ currently running in basic, and it's a wd red plus 12tb. Shaking my head at this point.

[@MRForever-ub5pw]

Just FYI. Found the problem after watching a boat load of videos. Apparently under Hardware and Power there was a default check under the enable memory compression etc. I unchecked it and now getting full 111-114 MB/s transfer speed both ways from my wired computer to my new DS920+

[@gertwallen]

8:11 Hi Rex, in my DSM (latest version as of today) in the "Others" window there's an additional option under "Enable asynchronous read" that displays "Monitoring changes on all subfolders within that directory" and is enabled by default. What's your take on that option? Thanks

[@holger.gruenhagen]

I wondered the same. @SpaceRex

[@user-jy9xv4pe3g]

Hi, I am a new Synology user, Your videos are so so helpful to me. You have ever mentioned a bit about the SSD cash setting for DSM 7.1 that the read and write setting is suitable. It is different from DSM 6... I want more information. about it for MAX SPEED!

[@johnconley4118]

When running with 10GB, jumbo frame will speed up your connection. You can see the difference when testing with IPerf4. I would also recommend using Multi Channel to get more speed out of your NAS. I have reach up to transfer speeds of 1.7 GB using a dual port SPF+ nic in both my Synology and pc

[@SpaceRexWill]

Hoping smb multi channel comes to DSM later this year. Right now you can do it, but there is a bug that could lead to silent data corruption so I cannot recommend it to people yet. As for jumbo frames: when you have a fast network card, cpu, and switch you sometimes do not need jumbo frames. By having standard network frames you get higher 4k IOPS as small requests get sent earlier

[@ghostdogzx-1474]

I’m curious what drive configuration you’re using. I just got a DS1522+ w/ the 10Gb (E10G22-T1-Mini) w/ 4 WD Red Pro, and 2 Samsung 970’s. My main computer is the Mac Studio which has a 10Gb LOM. I’m running my Red’s in Raid10 w/ the two 970’s as read/write cache. I’m disappointed in how caching works. I was hoping the write cache would help with all I/O such as large video files on the writes. Not the case. So what I’m seeing is a max of 550MB/s on writes and about 1060MB/s on reads - which I believe is about right for a single 10Gb adapter. So in order for you to reach 1.7GB/s I’m assuming you’re using 2.5inch SSD or 6 or more HDD’s - in addition to SMB MultiChannel. Can you confirm? Thanks.

[@johnconley4118]

@@ghostdogzx-1474 I´m using 8x12 tb reds with 2x 512 nvme drives as cache. The read speeds is because that you have to copy the file a couple of time to get it into the cache. The first time, its's coming straight from the spinning drives. When I write, it goes directly to the cache and I get average of 1.2 Gb/s. I´m using a solarflare sfn5122f nic, which is a dual port sfp+. (X520-DA2) and Multichannel. I do not use link aggregation. I use jumbo frames and the nas, computer and switch which is all 10 Gb

[@ghostdogzx-1474]

@@johnconley4118 This was helpful info. In this case I’m still not sure why my writes are only 550Mb/s. Based on your info, I would expect about 920MB/s with a single 10Gb NIC at line rate otherwise there must be a bottleneck somewhere. I wonder if the reason you’re reaching 1.2Gb/s has more to do with you running more HDD’s than the cache itself? I’ll do some experiments and see if I can get line rate if I switch from RAID10 to RAID0 (as a test). If this reaches line rate it’ll tell me that my bottleneck is the HDD and that it’s not caching in the way I expected. Thanks again!

[@runcmd1419]

So I just tried doing an initial transfer on my ds920+ from a m1 mac mini with the included ethernet cable and it is only getting 20-60mbps transfer, mostly raw photos, so hundreds of 40MB files. Is this typical, or should I investigate the settings and physical connections?

[@dimitrisskigkopoulos5251]

Hello, i am facing an issue, i want for example to copy 5000 raw photos from sd to my nas, when i go into the folder and select all the images and paste to nas, i have a loading bar with preparing, but if i copy the folder and paste it it goes much faster, why this happens? and how i can solve it?

[@dominicdo]

Thanks this helped my performance. Can you make a video on how to transfer files from Cloud torrent to Synology?. I using Tranfercloud and Offcloud is this possible?

[@Wesmosis]

When should I press "clear SMB cache"?

[@gregandrews2800]

Great video. Lots of important details with explanations. Wonderful. I use my Synology to back up my home computers. This video helped me go from very very slow backups to very slow backups. This is NOT a criticism of your video, rather a criticism of Synology. I have a Gigabit network. Everything on my network is super fast EXCEPT this NAS. Why can't Synology help home users with this? Not expecting an answer form you. Maybe someone at Synology will read this and try to help out all us poor home users.

[@pgotze]

Disabling Transport encryption and Server Signing is the most important i guess, if you dont need it, disabling makes huge benefit, thats correct. Anyway, i do use Synology Directory Services for years and do not have any issue having these options disabled. Not sure, what exactly do you mean to keep encryption enabled to make Directory Service working properly? I did not realize any issues.

[@SpaceRexWill]

Ah looks like they now allow you to leave them disabled: “SMB Signing allows SMB communications to be digitally signed at the packet level. After a domain is created, this feature will be enabled automatically, which may reduce read/ write performance during SMB file transfers. To enhance performance, please select Auto or Disable from the Enable server signing drop-down menu at Control Panel > Domain/ LDAP > Domain > Domain Options.”

[@billycrowe4501]

I did all this and have a 10gig switch and inputs to my computers and nas and can’t seem to break 300MB/sec. Any ideas I’m trying to identify the bottleneck. Not the cables and I’m using 6 5400rpm drives in SHR2

[@Lothos_]

Awesome tutorial, you explained everything perfectly! Wondering if these changes would also effect Plex server. I noticed it gets slow when Closed Caption is turned on. It some cases it just keeps blanking the screen out and not able to display. When looking at the Synology NAS the processor is at 100%. So doing Closed Caption just goes nutz. Hopping these performance changes you recommended would fix that. Thank you!

[@SpaceRexWill]

So the Plex thing is due to subtitle burn in causing plex to have to encode the video, which is highly CPU intensive

[@Lothos_]

@@SpaceRexWill I did the changes suggested in the video (and another video about plex server encoding h.264 and H.265 codecs. None of the chances solved the problem. Plex server freezes the video for over 10+seconds every few seconds (to minutes) when Closed Caption is turned on for the language selected (meaning Plex is allow you to select the language).

[@billycrowe4764]

is it possible to get ssd speeds like 2000/MB/s or 2800 MB/s? I'm curious if this is possible or how to get close. Is it purely a matter of using as many Hard disk bays as you can with 7200rpm drives? And using thunderbolt directly or would a Das be faster?

[@pascalkuratli84]

Hi, i have some Questions. I got the DS1621+ with 3x 10TB HDD and 2x 512GB M2 SSD for Cache. I use a 10GB network card and a 10GB switch. My Mac Studio is also connected to it, on which I cut 6k RED RAW recordings. Unfortunately, I never get the performance I want. I use RAID 5 and have 16GB RAM installed. This should actually be enough. I'm the only one accessing the NAS. My questions: - Should I enable Jumbo Frame? - Are there any special settings that could improve my performance? (Block size, cache settings?) - Would a network bond improve performance? (Use both 10GB ports?)

[@SpaceRexWill]

So first I would try jumbo frames and see if that will help you out. Also make sure that these other settings are done. The bond is not going to help you out if its just you. So this heavily comes down to what issues you are having. If you cannot get smooth playback (and you can if the data is on the internal SSD of the computer) then you may be running into a throughput issue. The jumbo frames can help with this, but also adding in 1 or 2 more 10TB drives will give you faster overall throughput. Its tough to say without seeing the system

[@DarrylZubot]

I am new to synology, got the DS1821+ with synology 10gbe card, hooked up to Mac Studio, I created the 10.10.10.5 network connection but it is extremely slow. It seems that my Mac Studio is connecting to the synology by wifi and not the direct ethernet connection. It takes about 10 min to login to the main DSM navigation, and if I change any setting it takes a few minutes to apply the change. Any thoughts?

[@jdittmarphoto]

Could you do this for optimizing speed for a off site system back up via VPN? Mine is painfully slow!

[@bladerealm124]

Any tips for speeding up file search speed on Mac? Or the best program to use to be able to locate files faster? I'm currently using Finder for my Synology NAS and it takes minutes of "Loading..." to finish the search. Is there a way to speed this process up and/or organize and go through my NAS files faster?

[@SpaceRexWill]

so if you are on the most recent version of macOS there is a bug that prevents this, but the fix is in work. You can index the folders though universal search on synology and it makes searches much faster

Hey Will, thanks so much for these. I have a q. I've just upgraded to a DS1621+, and a new mac studio. Both have 10gbe ports. I'm running 3 x 4tb ironwolf drives in SHR 1 array. Jumbo frames is enabled on both NAS & Mac, yet I'm only getting read/write speeds of about 280, which is really disappointing. Any advice as to what I'm missing? Other than some NVME caches...? Thanks so much man, will sling some dollars your way by way of thanks

[@SpaceRexWill]

Checkout your disk usage when you are doing a copy. having 3 drives in SHR1 means that only 2 drives can be read from / written to at a time. This puts those speeds ~somewhat~ in the expected 300-400MB/s of 2 drives in a RAID. Likely adding another disk (if your volume utilization is above 90% during this copy) would get you 50% more speed

[@iainpennington1852]

@@SpaceRexWill Thanks so much for this Will. Have ordered 3 more HDDs, hoping this will help. A problem I keep running into, every time I turn my mac on, is that SMB mounts over wifi and not over 10gbe ethernet. Everytime I have to disconnect wifi to force it to use network cable. Is there a setting to always force it to use ethernet? Really appreciate your help my friend.

I understand why you are saying to drop AFP and switch to SMB (even Apple going this way). But my experience is AFP simply works better. Our use case is we are using 3x locations with Synology Router's Site to Site VPN with maybe 10 AFP Shares and for the last 5+ years it has been rock solid. And, I have another application where I used SMB with macOS Shares. I was running a Linux VM on top of vmware fusion and using large files shared to the Linux VM and they kept getting damaged (no idea why). Once I figured that out I switched to using Linux NFS to Synology Shares and it has been rock solid. So, I have some negative experience with SMB. Maybe it was Samba on Linux or some other issue. I was just trying to have fast i/o to linux from macOS SMB Shares. Now, I am moving those Linux applications to Synology VMM on the same box but will still use NFS Shares. MAC hardware is faster but with Apple dropping INTEL and I need INTEL for this application I decided to give Synology VMM a try. Also, upgrading to DS1621xs+. Maybe I will switch a few of my shares and test SMB again that would not affect my main applicatoin of the NFS Shares. Lastly, thanks for all your videos. Have watched a number of them and they have been helpful.

[@SpaceRexWill]

Totally agree with you, there are just some cases where AFP is better, but they tend to be a bit more niece. One thing I would look out for is apple silicon macs. It seems like apple did not do a great job porting over AFP to apple silicon and has quite poor performance (just small testing)

Not using SMB 1 seems to be the prevailing wisdom but I found that without it, some network devices would not appear on my Windows 10 desktop's File Explorer. I do wonder if it's possible that another network setting has caused that problem though. My DS920+ is not exposed to the internet and is used on a home network for a very modest amount of file sharing, backups, and multimedia. As a result, I think the risk is pretty insignificant.

[@SpaceRexWill]

I am guessing that those network devices are quite old, or something like a SONOS speaker. I would recommend trying to get to a place where you can disable smb v1 as it’s not just a security issue for someone breaking into your NAS but also your computer. There was a bug that allowed for remote code to be executed on a computer with smb v1 enabled.
