I'm getting alot of
[2014-03-06 22:02:36] Stratum connection timed out
[2014-03-06 22:02:36] Stratum connection interrupted
this evening.
Is it my connection, my cudaminer or the pool?
Also, When i try to add my cpu's 40khs to my gpu's 170khs, (by running 2 different worker) over the course of the day, the site report i've been doing 130khs(with 9khs wasted). Why does it look like my cpu's khs is being substracted from my gpu's work?
data is slower to show a true picture of lower hash rates because samples are sparse compared to higher hashing set up, so it would be hard to pin down what you are experiencing. I would start by checking the BTC address in your cpu miner.
