I like to announce a modified version of the CPU-Miner. It's on average about 1000% faster. Yes, no typo, +1000%.

The trick is to only search for gaps that meet the criteria (pool = is a share, solo = is a block) and quickly discard others. 10g/h and 15g/h are not calculated anymore.

The source is available here:

Check and compile yourself (just "make" will do the trick).

I hope to see new large gaps and expect some donations (could have just used it myself!):

When using the pool make sure to point it at the port for GPU-mining (=higher target, less load on the pool).
