The BOINC core client giving lower benchmarks. We're talking optimised apps were giving about the same as normal BOINC apps.

The disadvantage before was about 50%. (linux clients getting 50% less credit) Thats why a couple of the big crunchers jumped back onto Folding where everyone get's exactly the same points for the same WU regardless. Avoids the credit lottery.

I did hear they'd improved it but by how much I don't know.
