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.
