/proc/meminfo accurate?
Hi All,
I've observe something on my system (host) for a while now and unable to put my finger on the problem.
I've notice after doing some cross compiling( building kernel, apps, etc) my system gets sluggish and drags.
I did a /proc/meminfo and noticed I'm using quite a lot of memory, much more than expected considering what I'm running. I looked at the meminfo on my target and noticed the same thing. However, on my target, I could consider that as a memory leak on my application, but on the host?
On the host I have a few things running mainly server such as nfs, dhcp, tftp etc. I also run scratchbox.
Does anyone have any ideas why I'm experiencing this and does anyone have possible solutions? Does this memory usage looks right to most of yo?
I'm running sarge on 2.6.8.
This is what My /proc/meminfo looks like: (for a 768M Ram, that's a lof of usage for my system)
