Right. Great then. :D

I would imagine that most "pure" Linux Folding machines are dedicated Folding rigs, Folding exclusively or nearly so. That's the case with my Linux boxes.
But wouldn't folding and gaming at the same time really drop the folding performance?

If you game two hours per day and folding performance is reduced by 50%, you lose 1 hour per day of production. If you turn FAH off while you game you lose 2 hours per day of production.

Oh yes. Good point. :e) Although I don't know how the games will respond to that.

If folding in a VM, be sure to set its ungrabbed priority to idle in order to minimize the effect on games. Also set the VM memory allocation to the lowest amount possible and still avoid swapping, unless you have a lot of ram.

How much memory should I give the VM for SMP folding?

With a full Ubuntu install and the average WU, 800 MB is usually enough. On a machine with 6 or 8 GB of ram, I'd give the VM 1GB, so as not to get caught out by some future WU that uses a lot of ram.

Unfortunately I only have 4GB, but I'm planning to upgrade to 8 in the near future. I'm gonna give it 1GB then. 3GB is a bit tight but I think still manageable. Thanks ChasR :D

It depends on the game, WU that is currently running and the machine that it is running on, for my games i usually leave folding running - only when i i'm running dawn of war do i shut down f@h

Three months ago I had Q9400 processor, which worked with VM + Ubuntu 11.04. After a conversation with Grandpa_01, I tried Ubuntu 10.10. With/without BFS Scheduler, PPD was less than 11.04.
With Q9400 the difference in PPD between Win7/Ubuntu 11.04 was about 9-10%.

After the upgrade (see signature last row), this difference was already Wn7/11.04 ~ 15%. My computer is dedicated (+3-4 hours surfing on the Internet).
If any significance - VM ware/Workstation/v8.0.1(1.0 GB RAM for Ubuntu).

Sorry for bad English :)

I've not seen a difference of more than 1% in the various Ubuntu flavors, when comparing frame times on the same WU, and I have had up to 20 Ubuntu instances of various versions going at one time. If you like the Unity desktop then 11.04 and later will work fine. If you don't like Unity (want a more windows like environment), use 10.10 or 10.04. I see about a 15% improvement with VM/Ubuntu over Win SMP, on the same WU, on any version of Ubuntu back to 9.04.

The same project - 7501.

For Win7 average TPF - 172 sec.
For Ubuntu average TPF - 145 sec. (172/145 ~18%)

According to SMP bonus point calculator:

Win7 - TPF - 2:52 min - 18 429 PPD
Ubuntu-TPF- 2:25 min - 23 800 PPD (PPD percentage difference - 29%)

I have no explanation why it is so much difference to me.
In Win7 I only have MS Office and several small programs installed. AV is MS Security Essentials.

That sounds great, so 11.04 makes more than 10.10 in your case. Have you tried 11.10 or 12.04?

Yes I'm a fan of unity :lol: I already have ubuntu 12.04 running on my laptop (I don't use it for folding, at least for now), and seeing the improvements you guys reported (although some report less) I'm gonna install it on my desktop.

Wow awesome :eo . 29% is a huge difference. I can't wait to try it myself when I have time. Hopefully I'll see such a difference.

Thank you guys for taking the time to help me on this. Really really appreciate it. :)

Some games may lag noticeably and others probably won't since FAH is going to be consuming only CPU resources which run at a very low priority. (Hopefully your VM will be set up to accommodate this properly.) If it lags enough to bother you, you can probably give FAH a smaller enough fraction of the CPUs that any lag becomes unnoticeable -- and that still may leave something for FAH.

I'll do that. :D Right now I'm booting ubuntu and I can't even download the linux client. I go to folding.stanford.edu, and the "other platforms" link doesn't do anything.

And the main link isn't even there. Confused :?

Works on my computer. Google Chrome with AdBlocker running on Windows 7 64-bit SP1. I think you may have Javascript disabled or something like that. They use some fancy scripting for that which doesn't seem to show up on your machine for some reason but works for me. Hmm.
