The p-state governor can make a huge impact on results.

this is why we recommend users change their p-state to performance when playing as the differences can be dramatic, it’s more noticeable on Vulcan games than OpenGL however depending on your setup you can easily remove frame drops and increase overall performance by 10% plus.

Right but for the purposes of this comparison though was just an out-of-the-box OS comparison.
This was the post in question.

Sure there's some overhead of the powersaving mode, but it shouldn't make a huge difference, as we can see from the xonotic benchmarks which probably are more cpu-limited as the unigine benchmarks.

Of course this was not anything about your all default out the box testing method. I have found a lot of people think the intel_pstate will have little effect where in reality with games it can be a massive factor. I was just providing a little extra background and examples to how p-state does effect game performance.Michael Larabel

The people saying it makes a difference is right. It can also impact server latency, so be sure to test CPU performance bias on your web servers as well. Of course it makes a difference to wattage, too, and that may be a big consideration if you're paying for it, or having to cool it (as in Michael's basement den).
In many cases that's someone else's job, though, and part of what you pay for - so why pay the same for less?
If people would stop turning C-states off in the BIOS (they're a crucial performance tool for enabling turbo-boost, as well as saving some power) and turn performance bias on, they'd have the best of both worlds. The impact can clearly be seen on a moderately-used server.

My internet connection seems to work very well in some applications, and terribly awful in others: I checked the speed on speedtest dot net and the result is 350 mbps download and upload, I’ve downloaded a 4gb opensuse iso in 10 minutes, however the output from the speedtest-cli is about 1 mbps download and upload, and I get that same speed in some steam games, when installing packages from pamac it took me 1 hour to download 700 mb. I googled the issue and maybe it could be related to ipv6 or...
