Ok, I guess my micro-benchmark is too micro for you, but I like to use "time cat /dev/urandom | head -c 10000000 | bzip2 -9 - | wc -c" I have a page with various results online somewhere, probably at http://atrey.karlin.mff.cuni.cz/~pavel/quickbench.html Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
