Version or versions? I mean, even better than 7.4? I read some tests that
performance of 8.x is in some statements a big regression (runtime 25ms on
7.4 while 8.x needs 1000ms (1s!))
It sounds that you have done some real world and sensible tests, that's why
I'm asking. I don't give too much for synthetic benchmark results, but a
factor of 40 surely would be noticable in real world...
