Are they working on the exact same unit? Can you post the beginning section where it has all the config info and unit info?

Guess not, but I thought they were all suppose to be very very close in terms of work.

Hmm, I'm not sure how different they are, you could always just copy the folder over so they use the same one.

Interesting, that's a pretty surprising difference. What have you done to each, is that just a fairly stock install? I run Ubuntu in my VMs, but I cut out a lot of **** and just have it boot straight to command line, no ubuntu-desktop.

Default install of Ubuntu w/X running.

Default install of Gentoo off the 2008.0 AMD Live CD. CLI only.

I'd hope X is not that much of a hog. For anyone that wants to try Gentoo to see if it is faster there is a virtual appliance that you can download.

http://www.vmware.com/appliances/directory/1328 EDIT: Actually, I'm not sure if that is a 32 or 64 bit VM.

hmm... maybe try to stop X (/etc/init.d/gdm stop) and try again.

but like you said, i can't imagine that X uses enough processing power to make that much of a difference...

very weird.

I've run notfred's folding appliances(no X) and compared the TPF's to running the same WU in a distro with X, not running X doesn't seem to make a really big difference

Makes doing anything graphical very difficult when you kill X.

Post this up in the Ubuntu forums and see what they say.

I would try it with CLI only first and see if it changes anything.
