Performance on recent app

I have recently deployed an application for a client on Linode 360, with
nginx and 4 mongrel servers. I am not caching and data right now,
mainly because the client won't have enough hits to make it worth while.
After looking at the log files I was surprised at the low number of
requests/sec that I was getting, that were ranging from 2 (on inserts)
to 50.

Are things normally this low?
