[horde] PHP APC

[Andrew Morgan]

I recently upgraded our Webmail systems to the latest Horde/IMP/etc stable 
releases, and I have spent some time tuning the various pieces for 
performance.  We currently have 3 servers in a load balance pool:

(3) Sun x4100, two dual-core 2.4GHz opteron 280, 4GB RAM
Debian Etch (stable)
Apache 2.2.3-4
PHP 5.2.0-8+etch7

During the daytime hours of peak usage, the load average hovers around 1. 
Thankfully this is only summer term!  When fall term approaches I'll need 
to make some improvements or the students will probably notice a slowdown.

I'm looking at using a PHP accelerator to reduce the load and improve the 
performance further.  APC sounds like the way to go because it may be 
included by default in PHP6.  Does anyone have experience running APC with 
Horde with Debian Etch PHP5 packages?

Any feedback is welcome.

Thanks,
 	Andy
