We're running RT 3.2.2 on an ancient Dell 6300 with Dual PIII 500/Xeon
processors and 2Gb of RAM under FreeBSD 4.9-RELEASE-p11.  The box uses
disk attached via SCSI from one of our IBM Shark storage arrays. We are
using MySQL 4.0.16, Apache 2.0.50, mod_perl2 1.99r14 and Perl 5.8.4.  I
compiled MySQL with LinuxThreads and run the "huge" mysql config (this
host also has a 196 million row web log database).

We have just under 6000 tickets and no ticket display takes more than 10
seconds.  It probably has around 6 to 10 concurrent users.

The apache processes sit at around 55Mb resident and don't seem to grow

I think the memory and faster scsi disk will help more than the faster

No experience yet, but I'm contemplating moving to it reasonably soon as
I can't currently backup the stupidly large weblog database to TSM and
I'd like to try MySQL with native threads rather than the heavyweight
