This stuff is important

This line show how long my system is up and that is is being loaded.  I 
am doing some image processing on one of the cores as I took this.

top - 11:56:41 up 8 days,  2:51,  4 users,  load average: 3.00, 3.02, 3.02

This shows the number of processes and some basic details.

Tasks: 184 total,   5 running, 179 sleeping,   0 stopped,   0 zombie
Cpu(s):  8.3%us, 43.2%sy, 48.3%ni,  0.0%id,  0.0%wa,  0.2%hi,  0.0%si, 
0.0%st

This is important when things start being bogged down.  At home this 
weekend, my system seemed frozen due to the amount of memory being used. 
  I had used all the ram and almost all the swap.  My HDD light was on 
solid.  Before I added the extra 4gig of ram a few weeks ago, my work 
machine was using upto 7gig of swap from time to time.

Mem:   8201104k total,  8107008k used,    94096k free,   487656k buffers
Swap:  8385888k total,        0k used,  8385888k free,  4414100k cached


To get more information about top, type in:
    man top

Your results from top all show 0% cpu usage.

Top is a  continuously-reporting command that will give you an ongoing snapshot
of what processes are running on your computer and how much CPU power they are
using.  In its default configuration (when you just run top with no extra
parameters) the process at the top of the list will be the one that's using the
most CPU power at that moment.

Load top and sit and watch it at the exact moment that your computer is running
slow.  See what processes tend to be at the top of the list.  They may come and
go and change a bit, but you should see a pattern or a tendency for certain
processes to be at the top of the list.

Whatever is at or near the top of the list and using the largest percentage of
CPU power is your culprit.

If you leave out the first 5 lines of 'top' (before the list of
processes) you're leaving out a lot of important info, such as the
system load average, memory occupancy, proportion of time spent in
user/system state etc. It's important to include this so we can see
what's happening.
