Percentile95% filter problem

[Petthan]

Hello

I running Query studio 10.2.1 and I trying to do a report of utilization on interfaces. Everything works fine but when i want to filter on PCT95% it just wont work.
It work fine when i do it with only 1 interface on the report. When i adding another is will be stuck at loading screen.

I like to only show interfaces with where PCT95% is > 50%

Ive tried to cut down on loading data ALOT. So im pretty sure its not processing ability that is the problem.

Another question

How does Percentile95 work?
becouse i heared alot of different version on how it work now :S
