Some 2990WX users have been complaining about performance regressions in Windows, and we noticed some strangeness in our own Threadripper benchmarks as well. Fortunately, Level1Techs seemingly nailed down the issue in a series of articles from a few weeks ago, and pointed to Coreprio as a good solution to Window's scheduling issues. Techgage just put that solution to the test in a wide range of benchmarks, and the results are interesting, to say the least. Adobe Premiere Pro renders, which didn't scale with the 2990WX's cores in our testing, saw a massive improvement with Coreprio, while other programs like Blender didn't seem to benefit at all. They also compared Windows to Linux performance in Geekbench, and for whatever reason, saw a night-and-day improvement when switching to the open source OS. Does all of this mean that Linux is the best OS for a chip like the 2990WX? It's really hard to believe otherwise. To base that off of GeekBench alone would be nonsense, but we have other testing experience to back up those opinions. Blender almost always performs better in Linux than in Windows, so the fact that a many-core chip works better in the penguin OS isn't a huge surprise... Fortunately, using either DLM or Coreprio won't hurt your performance in other areas too much, but it's important to note that it can in fact negatively impact them. On the flipside, if you bought a 2990WX (or 2970WX) and are running against a regression, you shouldn't hesitate in giving the tool a test. Don't like the result, or don't need it active all of the time? All you need to do is simply stop the service from within the applet, and you'll be back to normal.
