> key distribution matters a lot That is true, but it is obviously not the problem for Mr snej. He gets good performance when he disables all checks one by one, but not with -d:danger. So his configuration is somewhat broken.
And note, -d:danger is enough, no need for -d:danger -d:release. We should not confuse people too much. Same for -d:release --opt:speed, -d:release already includes --opt:speed.
