I started CSG on my 2p 2670 on the 18th as my non-dedicated system for daily use couldn't run these WUs part time. Starting on the 18th the WUs were 6-7 hours now they are are over 12 hours reaching to above 1 day. There is no commonality to the WU size number.

All have the same 433-436mb memory size in Linux. Windows is all the same at 435-438mb
