Hi list,
I'm running Fedora Core 1 with 512 MB RAM and 1 Ghz CPU.
I noticed that even without any apps running, the machine seems to be using a lot of RAM and I can't figure out what and why.
Here's the top output
<snip>
You have a lightly loaded machine. No swap is being used at all and 100.0% isle cpu. Buffers/cache are used to optimize the system and linux will use ALL available memory before it uses swap. You still have 157MB ram unused.I suppose cached/buffered memory are "free" because free gives the following output
total used free shared buffers cached Mem: 501 344 157 0 103 110 -/+ buffers/cache: 130 371 Swap: 1019 0 1019
but still, what's using 130 MB of RAM ?
Here is the output of free on my system
$ free
total used free shared buffers cached
Mem: 513852 502644 11208 0 181972 183320
-/+ buffers/cache: 137352 376500
Swap: 1028152 91080 937072
I am running a lot of services and the system works well.
Don't worry about the amount of memory being used unless it becomes a problem and the systrem noticeably slows down.
BTW, mine also is running at 100% cpu usage constantly
