Hi.
My config:
gentoo linux "2005.1" on amd64x2 in 64-bit mode,
kernel 2.6.16.12
glibc 3.3.5(NPTL),
gcc 3.4.3.
I had not used portage for building.
I built two versions of postgres from sources:
postgresql-8.1.4 native(64bit)
and 32-bit with CFLAGS=... -m32, and "LD =
/usr/x86_64-pc-linux-gnu/bin/ld -melf_i386" in src/Makefile.global.
32-bit build runs much faster than 64 apparently.
What benchmark utility should I run to provide more concrete info (numbers)?
What could be the reason of that difference in performance?
Regards,
Roman.
