Looks about right if you are getting a single feed to the machine. You
won't get benefit from cache unless you have multiple sites sending you
the same articles. If you have a single feed, or multiple feeds which do
not overlap, cache buys you little to nothing. All you are getting here
is CPU and memory usage to no benefit.
