Hi,

=20

I have a couple of questions I=92m hoping we can get a little help =
with=85

=20

Firstly, we are running a mod_perl application on 4 separate servers due =
to
its bulkiness.

=20

2 x 32-bit servers (Debian 32-bit) with 4Gb RAM each

2 x 64-bit servers (Debian 64-bit) with 8Gb RAM each

=20

We have found each apache instance is almost double on the 64-bit =
servers

=20

Example 64-bit

USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND

www-data 9950 2.4 1.7 210324 141744 ? S 14:26 0:11 \_
/usr/sbin/apache-perl

=20

Example 32-bit

USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND

www-data 2336 0.0 2.7 117100 105908 ? S 15:14 0:16 \_
/usr/sbin/apache-perl

=20

Is this something we just put up with or have we done something =
drastically
wrong?=20

Is it worth installing a 32-bit distribution on the 64-bit processors? =
Will
the 8Gb RAM cause problems as 32-bit distributions if we did this?

=20

Apache is the standard install for each distribution with a few added
modules.

=20

Secondly,

How can I get a split/rundown of what is taking up so much memory for =
each
apache instance, 100Mb is a lot, let alone 200Mb on the 64 bit servers. =
I=92m
sure we are going wrong somewhere.

=20

=20

Many Thanks.

GS
