Very definitely. :-)

I found that adding more RAM made a huge difference in RT's performance.

from top:

  5:08pm  up 14 days,  9:09,  1 user,  load average: 0.00, 0.00, 0.00
62 processes: 60 sleeping, 2 running, 0 zombie, 0 stopped
CPU states:  0.5% user,  0.3% system,  0.0% nice, 99.0% idle
Mem:   903184K av,  890224K used,   12960K free,       0K shrd,   52892K 
buff
Swap:  530136K av,       0K used,  530136K free                  278536K 
cached



It was hitting swap pretty hard with 512 MB of RAM and going to 1 GB was a 
big win.
