Pokertracker, should it be this slow?

[pfkaok]

Is it normal that everything on my computer goes very, very slow when I have pokertracker running? Pages take forever to load, and just every proccess on my comp is very slow when I have it open, so it makes Party and Empire choppy when I'm playing as well... I compact it fairly often, but how big of a database is too big, in that I need to create a new one?
