Disk Usage and Cache Memory

Disk usage at 96G with only a few accounts, and no more than 10 domains. Also, memory usage is high! Which is most likely from setting up litespeed with memory cache, but how do I clean my system after uninstalling? As this was just a trial run.

  For the disk usage you'd have to look and see what is consuming the disk space. Typically to do this I suggest the following: cd / du -h --max-depth=1
  This isn't recursive though and will just show you the usage for the current directory. This will give you an idea where to go to look. cd to the next directory and run it again to see the disk usage allocation. As far as the memory usage, it doesn't look high at all, memory usage in Linux can be confusing, the following article is really helpful in breaking it down Help! Linux ate my RAM!

  That can't possibly be all of the output, it can take some time to complete but the bigger partitions aren't even included here.

  So /usr and /home are your largest directories from what I can see here. You can find where the disk allocation is in /usr or /home by moving into one of those directories and running the command again.
