Tycho, is this due to the varying DDoS on the website that is going on, or is there another issue. Prior to this start of the DDoS, my linux clients were the highest producing Mhash/sec and they are essentially reduced in effectiveness to 30%
The LP issue may be caused not by DDoS. Some versions of Ufasoft miner are trying to use LP incorrectly, thus we had to disable LP for Ufasoft miner at the pool side.
