I have compiled mysql 4.1.1-alpha with the icc compiler using the options intel reported in their case study pdf.
specifically '-O3 -ip -unroll2'
The compilation was pretty ugly and threw up a lot of warnings. I'm benchmarking now and I'll let you know what comes out of it. yonah

Great! Thanks for the help.
Here is some more info, in case it's helpful- these are all the compile warnings from the make:
my_thr_init.c(67): warning #266: function declared implicitly
pthread_mutexattr_setkind_np(&my_fast_mutexattr,PTHREAD_MUTEX_ADAPTIVE_NP);
^ ...
icc: Command line warning: ignoring unknown option '-fno-implicit-templates'
sql_string.h(20): warning #161: unrecognized #pragma
#pragma interface /* gcc class implementation */
^

Hi!
OK, i have installed a fresh RH9 (i had the cd's here, altough i use a SuSE 9 and Debian). I downloaded a fresh copy of mysql 4.0.18 and 4.1 (just to try). I installed a complete develompent environment (gcc, bison, yacc, m4, etc etc) and it compiles cleanly, again; with gcc, I will download the icc just to try =)
Let's see what happens! =)
Best Regards!
