Is there a performance issue with the pool?

I have been running over 51gigs for about 20 hours.

The site is registering 33,415.2 MH/s, and has been about that since i started last night.

if I take a snapshot of stats and diff the times/shares. I will get about 700,000 shares per day at this rate.  I should be getting close to 1000000 shares per day.

this is reminiscent of the performance of the pool a couple of months ago.  Was there a change made?  I pay alot for electricity, and I made calculations based on 2.50 per gig per day.  50gigs should get me about 120$ per day, not 87.
