ok i found out what is the real source of the problem. i really had a hard time to find the reason because both, oclHashcat-plus and oclHashcat, share the same multihash binary search routine.
after some tests i wanted to start a trace session. so i had to recompile oclHashcat 0.26 kernels and whoops, the speed dropped (in my example) from ~4000M to ~2800M???
that lowers the possible sources to just one: the AMD SDK. when i released oclHashcat 0.26 the SDK used was 2.3.
so i quickly recompiled new oclHashcat-plus kernels with SDK 2.3 and see there, the speed is much higher than oclHashcat v0.26's.
conclusion: its good to know where it is coming from, but in this case i can not do anything more than hope AMD will put back whatever they do in SDK 2.3 in the next SDK release.
