Didn’t know about the turbo boost default, nice tip

[@popcorny007]

I just checked on my 6.3-3 install, the i5 4570 was boosting as advertised. Kernel is 5.4.78-1-pve. The /sys/devices/system/cpu/cpufreq/boost file is missing, so not sure what's happening there.

[@StarbornPhoenix]

@@popcorny007 I feel this might be an AMD vs Intel thing. My Xeon D-1540s are boosting just fine as well, at least according to intel_pstate. $ cat /sys/devices/system/cpu/intel_pstate/no_turbo 0 aka, turbo is enabled and working.

[@islo6865]

I literally had to stop this video at 1:10 to help a customer. The answer was to wait until the program loaded. Made my day.

[@brianmccullough4578]

Wooooo! Proxmox baby!

[@morosis82]

Software dev here, used to write for a web app that was targeted at enterprise users, including techs in the field, they are especially picky. We didn't automate the real devices but we did have automated virtual device testing using selenium for some of our more esoteric but well used workflows and had a selection of real devices to check things on when we changed something that might break things. That shit is hard, especially when the applications are modelled and transformed, and not all hand written. Got to make it work in a generic kinda way.

[@WidyaWalesa]

On-demand governor is getting better, rafael named it schedutil. Intel p-state is also rewritten to be governed by schedutil. I'm using it on 7h12 (2P) in linux 5.10.

[@atomicjango1460]

Love to see content like this on here!

[@stephenreaves3205]

I would love to see you guys compare proxmox and oVirt

[@stephenreaves3205]

@Dr_b_ which is why we need more tutorials lol I picked it purely for it's integration with openshift but I feel like I'm leaving a lot of features on the table

[@PhuketMyMac]

Great choice of background music and sound level. I’ll check that turbo boost activation on my Proxmox server ASAP.

[@gr33nbits93]

It's always a pleasure to watch your content.

[@marble_wraith]

It's gotten better in recent years, but yes virtualized testing is still worth it.

[@GeoffSeeley]

In some ways, the client server days had all the same issues but these days there are even more layers to the onion that is software development. Yes, welcome to my circle of hell!

[@NotMuchHere]

yeah, i dont like developing for other people anymore. The web does not work that way... for example (TTTTTT to move down the drop down to the 5/6 th item in the T's.) I dont care to test for 16 size devices ... i don't do data analysis on a phone .... !! :)

[@Nomaran]

Since I'm starting to ramp up building a new proxmox box this video is expertly timed. Thanks for the Turbo boost tip, I wasn't aware of that!

[@asabla]

YES! Been waiting for this one!

[@TechProGabe]

I love proxmox

[@motoryzen]

***** 60fps WENDELL!! YES! ALWAYS!! KEEP IT...PLEASE !! :D ******

[@ChrisBurnes]

Nice, might have to try proxmox.

[@Stephen-wh7vl]

Yeeeeeeet!! I would love to see a video where you explained the major differences in the virtualization platforms.

[@Stephen-wh7vl]

really I want to know all the nerdy stuff about domain 0 kvm and vmware and what the actual difference in different performance workloads amount to. c'mon what else do you have to do?

[@magellan124]

I find enterprise hardware to be way more interesting than the flashy "gaming" stuff

[@charlesselrachski34]

I think you will miss the colored lighting

[@rudysal1429]

Wish I knew even a quarter of how to do some of this stuff. Studied chem in college since people kept telling me software people would usually quite after a few years. Now I'm trying to learn linux to an admin level and python next.

[@MrBiky]

Engagement challenge I think the defaults on Proxmox makes sense in an enterprise environment, where you got lots of servers running. Usually CPUs have a certain frequency where they are running at peak efficiency. Turbo or overclock will bump the voltage a little (or a little more) and give you a performance uplift, but at a lower efficiency, so it makes sense from a cost perspective to disable turbo. If you got lots of servers, it probably isn't negligible, but for a home user or even a medium-sized company with up to 3 hot racks, it should be fine to enable turbo I think.

[@Level1Techs]

> Turbo or overclock ahahaahahah noooooo stop thinking this way. Turbo is * a fact of life * on modern cpus. its not an overclock it is absolutely positively stock behavior. it will not result in instability or conversely if turbo doesnt work you can return your cpu. its not an overclock. Some cpus like the xeon 8125M are skus for specific customers like amazon where the speed is essentially the "all core turbo" all the time. The default should be to operate how the cpu manufacturer expects. Not to disable turbo.

[@FilleMang]

@@Level1Techs Our 1650v2 cluster has a max freq of 3900. The 2650v2 cluster, 3400. Scaling governor is performance on all nodes. Have you found this to be broken or is this a "Proxmox with Epyc" issue?

[@MrBiky]

@@Level1Techs I believe I'm speaking with the editor, so I will be addressing accordingly. That is not what I said and this is borderline putting words in my mouth. What I said was turbo OR overclock, which as you mentioned are different things. I don't have a kill-a-wat or any wattmeter to check the consumption of a CPU full throttle with and without turbo, but if you have one, I dare you take some measures and see the consumption for yourself. And I also did not say turbo introduces instability and for a fact, neither does overclocking if the CPU is not pushed too far. >The default should be to operate how the cpu manufacturer expects. Neither Intel, nor AMD guarantees performance for permanent all-cores turbo, they only do for the base frequency. They do mention performance "up to" due to turbo, but that is not a guarantee, but it's in certain scenarios. You _can_ get permanent all-cores turbo performance, but the manufacturer does not guarantee it. And as I mentioned, turbo affects overall power efficiency for better performance, which was my whole point. Not all cores are created equal and some cores require higher voltage to operate at the same clocks, which is why turbo exists in the first place.

[@Level1Techs]

​@@MrBiky The situation here with proxmox was that turbo was *disabled* That default *does not* make sense for the enterprise environment. The manufacturer (intel and amd both) absolutely do specify how long at what clock, on how many cores and how many watts. Out-of-the-box this configuration would run well under the rated TDP of this CPU because it simply wouldn't clock as high as it should be. This is not a sane default.

[@Level1Techs]

@@FilleMang That seems right, but you might double check. It may very well be that this is a default config problem that only affects Epyc.

[@andljoy]

Making VDI work with apps from yesterday and apps from the late 80s is a ...... fun task. 9 days to get it working till rollout of W10 VDI and i still cannot get smartcard passthrough working properly ( well the passthrough is working but authentication is broken )

[@davidg4512]

Proxmox! Woot

[@Seandotcom]

Love the proxmox content. Also, it seems like boost was enabled by default on my R5-3600 proxmox node, I just checked

[@GoetheNorris]

FreeNAS also doesn't boost out of the box, but powerd allows to enable it. Maybe a quick tutorial about that? It's essential for anyone running minecraft servers, SMB shares with 10gig lan or any other single threaded task really!

[@ewenchan1239]

Did not know that Proxmox's defaults does NOT enable turbo boost. Good to know.

[@Raymond6494]

Time to play with proxmox

[@tigerfish66]

Love PROXMOX, becoming a paying customer was an easy decision......forms essential part of our test lab......

[@MaxPrehl]

"This doesn't work on 3DS browser"

[@KeithPatton]

Hey Wendell, just a question about the choice of Proxmox over vmWare for example? What benefits of Proxmox (or downsides to vmWare) help the choice?

[@Designsecrets]

Just ran analytics on my site, 13% of the traffic used devices with screen resolutions of 375 x 667 and 10% used 414 x 896.....hence everythings going mobil now

[@philiprhome3824]

personally i prefer running docker on a lightweight image as debian ... that's the best solution in my opinion

[@AxelWerner]

Do sum on how to use/build a HA distributed file system at home, for use with kubernetes and or docker

[@TobyCowles]

I have docker nested in a container on proxmox serving stuff to the public internet... should I be worried? The sites shouldn't be a big target, it is mostly stuff for our high school computer club, but I still generally want to follow best practice and wasn't aware that their were security implications to doing that

[@ciaduck]

Holy wow! That boost thing is terrible. I'm wondering if it's a CPU specific issue though. Perhaps EPYC? Boost seems to be enabled on my server at home running proxmox on a Ryzen 2700. # cat /sys/devices/system/cpu/cpufreq/boost 1

[@monofuel]

I'm also seeing it enabled on default on dual opteron 6272's

[@UnreasonableSteve]

Seeing it as enabled on my epyc 7252, too, but this isn't anything like a fresh installation

[@includenull]

I develop for web, every time there is a report of something not working, once I confirm its working for me my first question is "are they on safari?"

[@ddpxl]

Where are the good ol' .."are they on IE6?" days ... smh

[@aquastias]

@@ddpxl At least, back then, you did not need Apple devices to test shit.

[@GautamKumar-vy1mw]

Why not XCP-NG instead of proxmox

[@dotLiket]

Proxmox has turbo as default on Intel CPUs on my installs

[@Banner1986]

I had several issues with the default config/setup of proxmox... for instance, it doesnt let you define the stripe size on install, so I had to set this up prior. Did they expand the installer capabilities to allow this via the UI?

[@finarfin9939]

Why do you have a jet engine in your server room? Also Level1Woodworking when?

[@cig_in_mouth3786]

You are right wendel. Tested via geekbench on osx qemu. Let me try with my drone docker i will report you back

[@M1America]

What can't you run on docker, that you would need a VM for?

[@Level1Techs]

sr-iov workloads, vdi, etc. webgl automated testing helps quite a bit to have accelerated video for example.

[@randomname3566]

@@Level1Techs I'm not sure how much configuration it requires, however it is possible to pass a GPU into LXC/Docker afaik

[@UnreasonableSteve]

NFS, for one, is something I wouldn't containerize. There are also situations where you need to run a different kernel for certain workloads (e.g. Windows for some things, OSX for others, BSD for others, and I'm sure there are other situations where you'd want to run a specific linux kernel separately from the host's)

[@M1America]

@@UnreasonableSteve Why would you containerize NFS when you can run zfs set sharenfs="on" /pool/filesystem and then just open the port and it works. Run that on metal. Cringe. I use this feature except with SMB for certain datasets such that my family's windoze and mac computers. I get your second point though. Im not a developer I just setup cool smarthome stuff so I would never need to switch back to windows.

[@UnreasonableSteve]

@@M1America I wouldn't containerize NFS, that's what I said. Sometimes it doesn't make sense to have your virtualization/containerization host acting as a NAS. Sometimes it doesn't make sense to run ZFS at all. The only cringe here is thinking that everything fits perfectly into only one golden use case.

[@janedoeYT]

As a web developer, we just force everyone to use the latest version of Chrome and tell them to shut up lol (at least in my previous 2 companies)

[@OldKing11100]

My question would be: Is a Single Rack Server more redundant/stable than 3 (Desktops) Consumer Nodes using Ceph + 10GB Dual NICS + ECC UDIMMS (as allowed by AMD)? The ultimate goal is of course to use Three Rack Servers.

[@jj-icejoe6642]

No

[@jj-icejoe6642]

Ceph is better

[@savagedk]

Odd, I run a proxmox setup with a 3800X with GPU passthrough and if I check the cpufreq it turbo's just fine to 4.4Ghz

[@kortaffel]

Hey Wendell, instead of that liquid card that has a pcie switch on it, can you use a 4 x nvme card that bifurcates a 16x slot into 4x4 lanes? (this card that expensive asus threadripper motherboards put in the box) I wonder if such a card works in a server too (does the bios support splitting a 16x slot into 4x4)?

[@UnreasonableSteve]

Many servers do support bifurcated PCIe slots - I run an asrockrack epyc motherboard at home with exactly one such 16x=>4 nvme cards

[@Level1Techs]

yes, a simpler 4x4 bifrucator can work, there are uefi options to configure the slots as such.

[@TimotheFillionBrunet]

Look like the boost only apply to amd cpu not intel xeon. Turbo is already enabled

[@93davve93]

How dit you end up installing docker? In a VM?

[@hauby121]

Is ovirt any good compared to this?

[@MrNoBSgiven]

I've been playing with proxmox for a while on my spare Nuc. What I like about it is the ease of LXC and VM creation. Same goes for virtual disks. And then comes the ugly: simple (one would think) tasks of ups or email.sms notifications setup (vide Synology DSM) simply doesn't exist. Total fail in my opinion. Providing high-end features that only handfull of geeks can appreciate, but skipping basics like web interface for email notifications is just an unforgiving shortcoming. What say you @Level1Linux ?

[@hongtanke]

That explains why my proxmox setup doesn't run as fast as the esxi one
