The reduced crunching time gain is relatively small using the BOINC 64 bit client. But, the way the benchmark system works, in fact at time of awarding credit (points), it is often responsible for adverse affect. Too hi claims are causing for the credits not to be computed from average but from the low claim in a quorum.

Generally, a large component of the Benchmark measurement is the integer test, whereas the WCG work is floating point intensive. The 64bit Client is sadly amplifying the differential.

Just forgot to ask it in first post.

So none of the WCG projects use 64 bit work units? all of them are using 32 bit workunits? am I right?
