I doubt that 0.0% CPU usage and 5.3% MEM usage are the cause for the
bad performance.

How did you sort when running top?

After running top push x to highlight the column you are currently
sorting by, then push Shift+M to sort by memory and after that Shift+P
to sort by CPU usage. This at least should work with a default "classic"
top.
