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...

Thanks,
