computer performance

[sublime]

or in this case, lack of.

mine was just really really slow. i was four tabling but also had a few other sites up as well collecting data. here is what i had running:

two party skins
pacific
Handgrabber (pacific/PT add on)
PT (importing party and pacific HH's every 5 minutes)
gametime
Itunes
couple of excel spread sheets
couple word docs
a few internet explorer and firefox pages
trillian

what is the main culprit? i usually have this many going and it never seemse to be as slow as it was today.'

also, is there anything in general i should be doing on a regular basis to improve performance?

thanks
