Hi,
I have a couple of questions I’m hoping we can get a little help with… Firstly, we are running a mod_perl application on 4 separate servers due to its bulkiness. 2 x 32-bit servers (Debian 32-bit) with 4Gb RAM each 2 x 64-bit servers (Debian 64-bit) with 8Gb RAM each We have found each apache instance is almost double on the 64-bit servers 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 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 Is this something we just put up with or have we done something drastically wrong? 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? Apache is the standard install for each distribution with a few added modules. 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’m sure we are going wrong somewhere.
