[horde] Horde is really really slow on my machine.

Have you compiled PHP with mcrypt?  This can make a big difference.

As far as performance goes, I have suboptimal equipment on my machine (AMD
K6-350/160 MB of RAM/old 72-pin memory, etc.) and IMP/Horde is as fast, if not
faster (at least with HEAD), than any other PHP based open source mail server
out there (i.e. squirelmail) at least in my informal benchmark tests.  So if
your machine is having 10-15 second delays in loading pages, it must be
something on your local end because it works fine on my slow setup.
