This parameter makes me remembering that I made an optimization in the FG branch to allow a thread to take over the next batch of strategies without waiting for all others threads to be in the same stage. Actually, in the main branch, if you look at your CPU utilization you will see the overall usage periodically decrease until only 1 CPU is in use and then start again will all CPU at 100%. With my optimization, the brute force optimizer is always using all the CPU power.
