Hi All

I have a powermac g5 2.x2ghz cpu unit, with six gb of ram.

My question is, when I use firefox, thunderbird, final cut express all at the same time, it seems, I can max out the cpu's but not the memory. The memory usuage sits constantly at 2.5gb of ram, with 3.5gb of ram free. Even when the video file I edit is 4gb in size, it seems not to load all of it in ram. for some reason it uses 1.5gb of ram, and the rest is swap.

I notice i/o usage goes through the roof also, but my ram does not get used.

Is this a feature or a fault. I assume if it could use all of my ram, or does it not use it all, and thrashes disk usuage.

Firefox has about 20 tabs open, and just uses swap also.

Certainly not a feature. The Powermac should be able to cope with a shit load more memory than that before it can't address it all.

I'll let someone smarter than me offer some troubleshooting steps but you're right that something's not right.
