I can confirm that tendency (from the impressions so far). But my intention is now to get some numbers to get a quantitative statement. Unfortunately, the Intel compiler performs far worse on 64bit Architectures than other options.

Could you please elaborate some HowTo use the icc? After extensively using perlbench, I came to the conclusion that gcc 4.x sucks and tried icc. Unfortunately, I'm getting lots of these:
icc -L/usr/local/lib -o miniperl \
miniperlmain.o opmini.o libperl.a -lnsl -ldl -lm -lcrypt -lutil -lc

Here is a message I sent to the mod_perl list with my results from the test.

Sorry, I didn't have any trouble compiling with it so I can't tell you what the issue is. I was using a 32-bit processor -- Pentium 4, I think.
