With this I measured about a 5% improvement in 0.94, so it would account for half of the improvement (although the runtime variance in the runs is pretty high). Would be nice if somebody else could do some measurements. was (Author: lhofhansl): When I measured this the difference between 0.95 and 0.94 (latest from branch) was about 10%.
