Linux 2.6 And Hyper-Threading
David Peters writes "2CPU.com has posted an article on Hyper-Threading performance in Linux. They use Gentoo 1.4 and kernel 2.6.2 and run through several server-oriented benchmarks like Apache, MySQL and even Java server performance with Blackdown 1.4. The hardware they use in the tests is border-line ridiculous (3.2GHz Xeons, 3.2GHz P4 and P4 Prescott) and the results are actually quite interesting. It's a good read as he even takes the time to detail his system configuration all the way down to the CFLAGS used while compiling the software."
Ok, Time to redo the benchmarks, Kernel 2.6.3 is out.
[joking]
Be nice when we see some nice Opteron benchmarks vs the new Xeons.

I did some informal testing between VC++ native and C# to .Net bytecode. I had a little loop calculating primes. The native C++ kept everything in registers, while the CLR made everything relative memory accesses to BP. I figured that would devastate performance, but on the Pentium 4, it was only 5% slower! It seems to have an L1 cache that's as fast as the registers. That will certainly make it easier on the compiler writers.
oops you just violated the VS.NET EULA by posting a performance benchmark. shame on you!
What are you still running on? A 486?
I will *not* answer that question!

Treehugger? Treehugger... Treehugger!
My entire lab at school is filled with Dual 3.2GHz Xeons with Quadro fx 1000 cards. People have those types of machines... or 100 of them.
