Is Resolve faster on Linux?

After installing Windows 10 Cumulative Update KB4494441 a few days ago, a 30 minutes 1080p@25 timeline played back at only 5 to 10 fps.
I uninstalled the update, no change.
Then uninstalled more updates and reinstalled Nvidia Driver 430.64 for Quadro, no change.
Then reinstalled the recent Win10 updates, including KB4494441, playback back to normal.

Do these things happen on Linux?
Is Resolve faster / more stable on Linux?
If yes, which build?

Thanks,

The recommended centos 7.x is pretty solid, but at the end it goes down to the system build, cpu/gpu/hdd

Once configured, Linux is quite stable, but it comes with its own set of issues setting it up.

Linux doesn’t suffer from anything like the Windows Registry that degrades performance over the course of a few months and necessitates a “reset” every few months.

I run Glary Utilities to clean up the registry and fix the broken shortcuts on a regular basis, it helps a lot.
Also scanning for errors on the HDD/SSD and optimizing them helps a lot.

Thanks for your answers.
@Seth what do you mean by: necessitates a “reset” ?
A fresh installation of everything after formatting the system drive?

My editing machine has just a few professional applications installed and connects to the web only for windows updates.
CCleaner indicates one or two registry errors every month.

I am not familiar with any Linux GUI. Can you point to a relevant Resolve Installation tutorial for the latest CentOS?

@Misha I use only SSDs for system and data (HDDs for backup). I am not aware of the need to optimize SSDs, they have no performance impact from fragmentation.
What do you mean by (periodically) optimizing SSDs?

CCleaner is very aggresive with cleaning, we stopped using it.

Optimizing a SSD is the same a Trimming.
We check our SSD's for errors and optimize them after a heavy workload(the scratch drive) and/or a lot of software updates/installs and de-installs (system drives). It makes a huge difference when you have never done this bevor.

With general computing, I find that everything goes a bit haywire on Windows after a few months. Windows 10 has a built-in function called “Reset my PC,” that keeps your data intact, but uninstalls every program. I’m not sure, but I believe it refreshes the Registry from scratch. Everything runs good as new after a reset.

Here are my installation notes for CentOS 7.6: https://sethgoldin.github.io/install-da ... ve-centos/

From your answers I understand that Resolve is not performing better and/or faster on CentOS 7.x given identical hardware setups.

So my next install will still be Windows 10 Pro hoping that taking care of the registry etc. will continue to take only very little time and effort.

With Windows, the problem of the registry is always the same. Over time, over installations, uninstalls, windows update: there is a degradation of the registry.

Personally, once every 2 years (even years):
A big full backup

I list all programs on printer

For all software with licenses =>
I disable them one by one
Then I unmount them

For others I do not do anything

I get the latest ISO image at Windows
I recover the possible updates of the drivers
I have my key for Windows 10 PRO

And finally, I format my HDD OS for a clean install
then I have 1 days to install all software important.

And I have a brand new and powerful system.

There is a theory that "bit rot" (leftover files clogging up drives, drive fragmentation, permissions issues, etc.) will slow down computers over time:

You can make a good case that it's a good idea to completely blow away a boot drive, then reinstall the OS and re-install every application, one at a time, so that the system is completely free of riff-raff.

I know of some screamingly fast Linux systems around town (for Baselight, Resolve, Lustre, and other systems), and they do this by stopping users from putting any extra files on the boot drive, plus they strip the OS down to its bare essentials to the point where the system is only designed to do one thing: run the color-correction program. You do that, and it'll generally run very well for a good long time.

. . . designed to do one thing: run the color-correction program.

@Mark, a Linux installation optimized to run all of Resolve's pages, not only "Color", looks like an interesting option.

I could not find relevant tutorials
Do you know where to find advice regarding minimalistic Linux configurations set up to run Resolve and Intensity/DeckLink cards?.

Seth's installation guide recommends to start with the CentOS DVD ISO package, which seems to be a "general use" CentOS.

Anyone knows where to find information about how to stripe down CentOS to its essentials, optimized to run Resolve 16?
