First of all, I'd like to mention that it was strange to see that
the server performance degraded by 1-2% when we changed kernel/userland
to x86_64
from default installed i386 userland/amd64 kernel. The operating system
was Debian Linux,
filesystem ext3.
Did you use postgres compiled for AMD64 with the 64 kernel, or did you
use a 32 bit postgres in emulation mode ?
