Memory overcommitMemory overcommitPosted Mar 11, 2011 7:10 UTC (Fri) by rvfh (subscriber, #31018)In reply to: Memory overcommit by epa Parent article: Delaying the OOM killer
Why use loads of swap space when I have 3GB of RAM to run a bunch of services?
A quick look at top:
So there are 689 MB of unused memory! Not to mention 1 GB+ of of cached stuff for the system to grab in case of need.
Now let's see the memory usage (top two):
So the two main memory users (systemsettings!?!) have committed more than half a gig of RAM, but use less than a quarter (I know these numbers are not perfect, but the idea remains).
And you want me to get rid of overcommit???

Isn't that the point? You have three gigabytes of RAM, more than enough to give every application all it needs and do so in a guaranteed way - not 'you can probably have this but you might be randomly killed later on depending on what else happens'.
