This is very very very true :-)! I just remebered one case with MySQL. When I changed the distro from Conectiva 10 (rpm-based ended brazilian distro) to Gentoo, a MySQL operation that usually took 2 minutes to run, ended in 47 seconds. This is absolutely vage. I don't have how to prove it to you. The old situation doesn't even exists anymore because I used the same hardware on the upgrade. And I can't mesure how each factor helped: compiling glibc and Mysql with good cflags, rebuilding my database in a ordered way, never kernel, etc.. All I know is that this process still runs with less than 1 minute (my database is larger now). I used the very same hardware: P4 3.0Ghz SATA disk without RAID. And I only upgraded because Conectiva's support to their version 10 ended and I need to keep my system up with the security patches.
