I understand your point exactly, but for this swing of the pendulum, there is a significant benefit with Linux.

And to answer your question, for 2% maybe, for 10-25% definitely. :-)

I'll go chase down the core version and 10% numbers if you want, but it doesn't change my point. Other factors have a larger impact than your OS selection...


I agree there are other factors and the application-level may have a greater effect on performance possibly due to compiler differences, flags used, or differences in codebase. However, I still believe that the OS has some impact as well. In fact, with the previous core release, I saw better numbers running the Windows core via Wine in Linux than I saw running the core natively via Windows. Here are some benchmarks I did last year comparing running the Windows core in Windows and Linux with p6900.

Is that because of Linux vs. Windows, or is that because it's a newer version of the core? I suspect the latter, but since we're not tracking core versions, it looks like it's the former, whether that's true or not.

For clarity, they were both running the same client version, same core, and same project. That's very much an improvement due to a switch to Linux.

Unless I'm wrong here we are comparing a true 64-bit F@H binary on Linux/FreeBSD vs a 32-bit binary on Windows.

Regardless of the O/S being 32-bit or 64-bit on Windows there will be no notable difference in performance on F@H due to the nature of the 32-bit F@H binary.

So I don't think we will see any performance BiGadvantages swinging back to Windows any time soon unless a true 64-bit binary comes to Windows. And it's difficult to compare A3 cores because Linux BigAdv had a lot of problems with A3, and I don't think we had any p6900 or 2685/2686/2692 units on Linux A3 to compare to Windows if we decide to go back in time as A3 BigAdv was pulled from Linux prior to these units coming out.

I'll be trying Linux on my AMD MC quad box tonight and see what happens. P6900/6901s run around 10:35 TPF on this quad 6168 box and 2684s around 14:00 minutes in Windows 2008 R2 Enterprise x64. If I extrapolate Tear's results to a lower clock speed setup (from 2.2 to 1.9) ghz I should be seeing TPFs of 7:45 - 7:50 if scaling is linear. Wowzers.

Welcome back Tear.

This is the expected behavior for now. Windows is not running the same codebase as Linux.

This, too, will change "soon"

Again, 64 bit gains nothing right now (yes, maybe later), so apparently, we will still see the pendulum keep swinging. ;)
