Mac Pro slow - why if there is enough inactive memory???

[Gloor]

Hi guys,

I don't understand this thing. Mac Pro is slowing down as its swapping etc. but I have plenty of inactive memory. What is wrong here? I'm on 10.6.3

here are pic. First is just normal and second is after about 30 mins

and another pic about 40 mins later. What is happening here? Why do I have inactive mem so big but the system is swapping like there is no tomorrow?

No Idea guys? My computer is slowing down drastically due to this and I am not sure how to solve it.

Don't know usually seeing....

Activity Monitor.app/All Processes/Sort by %CPU

Helps

Though at times, looking at the logs in console.app to see if there is something kicking out an error every second sometimes helps, since a huge log file can cause issues when the computer has been on a long time.

iFreeMem is nice tool. It makes your inactive RAM free again as OS X sometimes has issues to free uo inactive RAM

Computer was on for 14hours so that should be fine.

Why would I sort it out by %CPU? Anyway, the only thing that has a lot CPU is Maya 212% on 8core machine so that is not a problem

iFreeMem works nicely. Shame it is a trial. Also, it looks like I need to do that quite often so perhaps its Maya 2011 that is messing stuff around
My scene is not even that big (around 50MB and fluids are cached)
