Hi Guys, We have been running
our systems on high end Redhat ES 32 Bit servers without any sort of glitch. We
have now set up a 64 bit Athlon server running Redhat ES, installed the Redhat
PgSQL as well as the PHP5 RPM. I have been
experiencing incredible slow performance from my server, and am at a loss for
solution. Should I be moving back to a 32 bit system? This is the reply I have
from Rackspace: “Secondly
"sar" is showing that you are dipping quite a bit into your swap
space. When dealing with a database server, any time that you move from RAM to
swap you will see a massive performance drop, especially when dealing with as
much swap as this machine has. At its peak you were hitting 70%(700M) of
swap. Since PostgreSQL is unsupported I don't have any suggestions on query
optimizations. However, at this point upgrading your available RAM would be
one of my best suggestions.” Does anyone have any experience on
this? Most of the things I have read suggest that I move back to 32 bit but I do
think it’s a step backward – that’s if this can be supported. Regards and thanks, James
