Does OS Matter?

OK, I've overclocked the dually system and let it run overnight. FSB is now at 138MHZ. AMD Dual MP-2000 w/ 1GB ECC reg DDR RAM (PC2100)

Now the real question (as I sit here looking at my Solaris 8 media kit) Does the operating system matter? Are there any efficiencies to be gained by running the client on Linux versus XP?

Hi,

if you have the choice between windows (whatever version) and linux, take linux. It seems to be some percent faster.

When running on windows, DF produces lots of pagefaults (about 20.000.000 per hour on my system, P3-500). That can't be fast ;)

Greets,

Hi,
check http://groups.yahoo.com/group/distributedfolding/database?method=reportRows&tbl=1 on the old YahooGroup page. These benchmarks were done at the start of the project with an old version of the client and now discontinued proteins, but the basic pattern is that, yes, the Linux client seems to be faster than the Windows one, especially if you use the version compiled with the Intel compiler under Linux.
Happy folding,
