I was talking to Sava yesterday and he asked me to report this to the list.
We upgraded Ammannet from Campsite 2.1.5 to Campsite 2.5 . We got an identical server, installed Campsite 2.5 and designed the new ammannet site on it, then moved the old 2.1.5 database from ammannet server to the new one and then changed the dns to point to the new server.
With the new server, we notice that Campsite is using lots of memory. We have php wrapper installed on ammannet which we think might have something to do with the memory load. Here is a screenshot of the processes running on the server:
campsite instance is ammannet instance. You can see that it's using 116 MB of memory. awrd, intekhabat and cdfj instances are under development. There is only one person accessing these instances and each one is consuming 40 MB of memory. Also are the httpd instances caused by the php wrapper (since it opens an internal request to apache server). Every httpd process is consuming 27 MB or memory.
