I understand the concept and why things are cached, i've just never seen it
cache this much before.. usually on a machine with bearly anything running
on it (like this one) it uses bearly any memory at all. My concern is that
with bearly anything running on it i already have dug into swap.
Thanks for the responce, i just wanted to make sure their wasnt some type of
a memory bug.

Hi Shaun :)
* Shaun <[email protected]> dixit:
I see that free shows that 7.7GB is cached and i'm not sure why so
much is cached.
Because free memory is a *waste* of memory. Why leaving unused
memory when it can be used for caching? The kernel will (up to some
extent, I suppose) try to use all free memory for caching if no app
needs it.
If you have 8GB of memory, it's a bit difficult to fill it just
with the running apps, so the kernel cleverly uses the rest for
caching things so the system runs faster.
For example, I have 1GB of RAM, and even when I use X (seldom...)
I never eat up more than, let's say, 500MB. So, I have another 500MB
of memory unused: the kernel uses it as cache, and that makes my
system run much faster (I noticed a speed increase when I switch from
512 to 1G).
