crosscheck "higher BT precision" slowing down the build process significantly

if i add only simple MC test - 1M precision testing - my build task slowed down to 70k strats


this behavior is not logical - the slowdown should be max 50% and this will be only if every strategy goes through the ranking criterias of selected TF only


but i could have 0 strategies in databank after the filters and have this slowing down and from rejected stats i see that 1M precision was not used and filtered nothing


the slow down should be in a few percentage
