I hope you guys understand that it may not be possible to have 100% boinc cpu mining because security is the issue then. As we saw some f*ckers came and used it to exploit 0.5M grc. I know that Rob would also want to have 100% of cpu time towards boinc but it may not be possible. As Rob said it could be possible to use 1 thread with about 10% processor time to calculate algo. So with 1-core processor you would still have 90% for boinc.
