I have sucessfully installed Roundcube and love it, but it seems to be much slower than I would expect, even with LAN connection speeds. Are there any performance tuning tips or tricks I could use? -J
No errors that seem to be related to Roundcube: Code: [Fri Apr 11 19:54:24 2008] [notice] Apache/2.2.3 (Ubuntu) PHP/5.2.1 mod_ssl/2.2.3 OpenSSL/0.9.8c configured -- resuming normal operations [Fri Apr 11 19:54:25 2008] [warn] long lost child came home!

Looks ok. You could try to integrate PHP opcode cachers such as eAccelerator or Xcache into ISPConfig's PHP (ISPConfig comes with its own Apache and PHP in the /root/ispconfig directory).
Doesn't matter. you can either use the phpize command from ISPConfig, or you use a full path to the xcache.so in the php.ini, e.g. Code: extension=/path/to/xcache.so
