We don't have many users yet so it's not being used simulataneously by 
many users.

The system is running a few other services, but nothing too
resource-intensive.  It has 512Mb memory and 512Mb swap, but most of the
swap space is free.  Here's a sample:

 10:01am  up 34 days,  3:07,  6 users,  load average: 0.27, 0.14, 0.03
142 processes: 141 sleeping, 1 running, 0 zombie, 0 stopped
CPU0 states: 10.3% user,  7.1% system,  0.0% nice, 82.0% idle
CPU1 states: 32.0% user,  7.0% system,  0.0% nice, 60.4% idle
Mem:   513524K av,  471284K used,   42240K free,       0K shrd,   69136K buff
Swap:  526296K av,   21836K used,  504460K free                  199104K cached

  PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND
18013 webusr    23   0 29556  28M 15080 S    34.7  5.7   0:09 httpd

A few more details:

o dual PIII 500Mhz box
o apache 1.3.27
o postgres is running on another box - RHAS 2.1, 1Gb RAM, dual PIII
500Mhz

Running top on the postgres box, I see postmaster taking up 98% of the
CPU when I'm modifying tickets and it seems to stay that way until the
modify is complete.  So, maybe it is postgres afterall.

For now, I've resorted to using the email gateway as much as possible to
avoid the slow web interface.
