High RAM usage on idle

The RAM usage of my arch system has recently been very high, on start up it's about 150MB which although not too high used to be sub 100MB. However after web browsing, editing, using the terminal and other not very intensive applications the RAM usage goes up to 800MB plus. This is on a netbook (Acer Aspire one D255) that only has 1GB of ram so this is starting to be a problem as when I have several applications open it will really start to slow down. Closing these applications doesn't solve the problem either, as with everything closed after it went over 900MB it didn't drop below 800 and I had to reboot it.
Not quite sure what is eating up the ram as when I use the "top" command on idle awesome and X are using the most memory, and the tasks running didn't seem to add up to the ram being used.
Any suggestions as to what might be the problem and how to solve this would be greatly appreciated.

Re: High RAM usage on idle

That doesn't explain the slow down though.

As for the tasks not adding up, which column are you looking at in top?  The res column is how much physical memory is being used by that process and it should add up once you subtract buffers and cache from memory use.


I laugh, yet the joke is on me

Re: High RAM usage on idle

Not sure why it was slow earlier now, as I opened applications till it was using 920MB or so and it was running fine, a task must've crashed or something. And I guess I never realized how much buffers and cache take up, because adding up all the res columns it didn't even add up to 100 when everything was closed. Thanks for the info though, you learn something new everyday!
