High Memory Usage Issue

Hi, I am a little bit confused about my memory usage. I don't know if it is about xen virtualization and it can be a silly question to ask but when I type the top at linux shell, it says I am using 340 mb memory and I have 360 mb total memory by the way. And I just host only one web site now which its traffic is zero right now.

I am attaching my screenshot of top:

To make things short, is there anything wrong with this or is it normal?

Thanks very much.~~

Thanks for the quick replay. Now I understand the logic behind it.

type

free -m

in your shell it'll show something like this

total used free shared buffers cached

Mem: 348 339 8 0 29 215

-/+ buffers/cache: 94 253

Swap: 255 8 247

Tends to be easier than top. (In my case I'm using 94MB).

Don't forget swap, technically you're using 102MiB.

Lol yes, that's true 8 MB swap and 94MB ram

Memory hog!!!

I built my linode when it was still a linode64. Now it's a linode360 I have all that extra memory… but no need to change my software :-)

Damn that's an old node, what OS are you running on that? I think my ubuntu 9.10 runs around 30mb with nothing extra installed.

CentOS 4, fully patched.

Ah yes, mine was a 64 too! Good times. It's still rocking and rolling, although now it's a 720.

I haven't used CentOS 4 in a few years, maybe if I find I have some spare time on my hands I'll crank up a new node and have a play. :)
