Try taking a look at your CPU usage for each process. You can do this by
typing the following:
ps -aux|less
If you prefer to use "more" as your pager, feel free to do so. This will list
the processes running on your machine by order of CPU usage. The process that
is taking the most CPU power will be listed first. Take a look and make sure
none of these look out of the ordinary. For your normal processes (i.e. named,
httpd, syslogd, etc...) you shouldn't see any over say 2.0%. Now this is
assuming they are idle. If they aren't you will see higher percentages. You
can take a look at them as they are not idle by using this command:
watch -n 1 ps -aux
This will updat it every second. Use Ctrl-C to break out of it. I hope this
helps. Here's an example of some processes on my system which are idle:
