I could have sworn I read something on here about each thread defaulting to using too much ram, and there being a way to turn it down a touch. But I can't seem to find that thread now, I spent quite a bit of time trying different search terms last night, never did find it. I did find some good info though. Anyways, here's my TOP command list:
Sorry that's a bit large.. It's all of the processes running on my machine. Note how at the top it says I only have 4megs free, it seems to be hanging out around there, the buffers change from 2 to 6mb free. I see a lot of my processes list a large amount of virtual memory.. Especially the php-cgi processes (why are there so many of them?), is that virtual memory free to be given to other processes, or do they actually have it locked down?
It's amazing, it wasn't all that long ago that I felt 512mb ram in a Linux machine was very very generous, now.. It feels kinda tight. I'm hoping it's just imaginary, and there's actually plenty of free ram left..
