Is this at all times or are you doing anything special when CPU consumption is that high?
slkqt run only increases my cpu consumption up to 81% so the cpu fan is 6200rpm butt and my very slow machine ..... it lasts all the time when it's running slkqt ... app at the end of the machine is resentful and I have to reboot again osx lion
I found out that the Soulseek client really is hammering on the CPU, when you use the search. The moment you enter some searches, the CPU spikes like hell. I've seen it spike to 149% with multiple searches going on. When you remove all the searches and you're downloading several files, the CPU is around 1%.
So the root cause lies somewhere around the search function. I'm on a new Macbook pro, OS X Lion 10.7.2
