[hobbit] Hobbit Server performance

1. Linux tends to gobble up whatever memory thats not being used for buffers
and cache, so on Linux boxes using nearly 100% of memory is normal. Use the
"actual" reading to get the memory that is being used not including caching
and buffers.
2. is normal, Hobbit is very network intensive.
On the bb-test results, it looks like your DNS lookups are a little slow and
your ping tests are taking a little longer than I would consider normal. I
am running Hobbit on similar hardware as yours, monitoring over 600 hosts
and have similar times for the DNS and ping.
Thanks,
Larry Barber
