I think this is why HT on xeon was slower coz it reports 4 not 2 processors and often its compiled with just 2.. i wonder why.. intel guys here? ;p
"The Xeon results are a little more interesting. Look at what happens when we enable HT and run with 'make -j 2'. It actually takes longer to compile the code with HT enabled! Since issuing a 'make -j 4' with HT enabled seemingly fixes the problem, I'll assume the previous results are due to some scheduling confusion as I did tell the compiler to issue two simultaneous processes but we had 4 logical processors awaiting work. The Xeons are the big winners in this test; as we went from HT disabled and a simple 'make' to HT enabled with 'make -j 4', we got a ~57% decrease in overall compile time. That's impressive." Im also looking at using itanium series, anyone have experience?
