In response to: Processor optimization compile options?  (Josh Berkus)
List: pgsql-performance

Starting from 7.4.1 on P4 and FreeBSD 5.x (exclude 5.0 - gcc in this
edition have optimization error)
I use next configure command
----------------------------------
./configure --prefix=/opt/postgres-7.4.1 --with-pgport=5432
        --with-pam --enable-syslog --enable-depend
        'CFLAGS= -O3 -pipe -mfpmath=sse -msse2 -msse
        -mmmx -march=pentium4 -mcpu=pentium4'
---------------------------------
w/o any problem.
As I remember improvement as always task depended and
have 30-100%.

Best regards,
 Alexander Kirpa
