Can someone explain to me how to determine info from the 'top' command? What do the numbers indicate?
Mem: 4018500k total, 2930032k used, 1088468k free, 248776k buffers

left to right:
you have ~4GB of total memory available
you have ~2.9GB in use right now
leaving ~1.1GB free
and ~0.25GB of what's in use is in buffers (which is also available if needed).
there's also probably some RAM in cache so you've probably got more than ~1.1GB available
you can compare this to the output of `free` to get a better picture.
# top's output
> top | grep ^Mem
Mem: 3977936k total, 3910816k used, 67120k free, 471124k buffers
# and free
> free
total used free shared buffers cached
Mem: 3977936 3910676 67260 0 471144 2690976
-/+ buffers/cache: 748556 3229380
Swap: 2048276 252 2048024
3229280 or ~3.2GB (in my case) is the accurate measure of free RAM

This wasn't your question exactly, but you may find htop (pacman -S htop) much easier to read.
