when is swap allocated
I was just wondering when/why swap space is used. I rooted around a bit in the various sources of documentation, but didn't find what I was looking for. The reason I ask is that swap is very rarely used on my system. Most of the time, the results of free look like this: total used free sharedbuffers cached Mem:128300 125204 3096 91920 2784 61060 -/+ buffers/cache: 61360 66940 Swap: 273024 4344 268680 Maybe I should be glad that there is little need on my system for swap, but I'm a little surprised and worried that something is not set properly.

AW: when is swap allocated
Well from my point of view, I'd say be glad. And it is not so surprising. I've got three machines running Linux and one Windows NT-System - all of them with 128 Megs of RAM and - surprise surprise - the only PC that does swapping is the windows NT system. Linux has a great advantage in Memory-Usement over most other Desktop (and even some Server) OSes So you propably shouldn't bother - besides there is rarely anything you could do about the way your System uses his swap-space. This is part of the memory-management in the kernel and it's mostly written in assembly.

Re: when is swap allocated
that is perfectly normal, linux is incredibly efficient at using memory. my main server has been up almost 6 months and is used _a lot_. and my mem stats: total used free sharedbuffers cached Mem:127544 119664 7880 100528 6016 34736 -/+ buffers/cache: 78912 48632 Swap: 261496 7604 253892 dont expect mem usage to go too high unless your doing extreme stuff..i keep a lot of swap for emergencies. incase a process gets outta control i got plenty of room .. nate On Fri, 21 Jan 2000, Brian J.
