Are you mining PPS or DGM, NorCal?
On another note, I think I finally beat the DGM bug into submission... I am running an isolated test server with a couple million shares over night to see what happens and if the numbers jive. If they do, we are on our way!

I am pleased.
For now, PPS. I've been on a PPS system since I've started mining in general. Haven't made the plunge to try DGM yet.
My mhash per worker on PPS is yo-yo-ing all over the place. I'm just chalking it up to your recent work with pool improvements, hopefully.
