I pushed a new commit with sieve optimizations. It appears to generate larger performance improvement on systems not heavily crippled by v0.1.0 miner.

Give it a try. Please note this version has a slower warmup period.

I had a noticeable decrease in PPS from this update ( ~1/10th of PPS from original release). I'm running a Core2 Quad. I realize PPS isn't a great measure of efficacy but the decrease seems pretty consistent and dramatic (15min thus far).

Is the "slower warmup period" longer than this, Sunny King??

Maybe wait a bit longer, what's your pps on core2quad?

It was 70-150pps with the original setup, then went down to 1-10pps with your updated .cpp and .h files. I switched to the mikaelh qt and d files now (retaining your .cpp and .h files) and I'm up above 1000pps.
