Yes I know. But the main point was, that the presented percentages
are more or less useless. The check latency is by far the only real
relevant information on that page. A fact, that makes the page seem
to be broken by design to me.

I do know, but that has actually nothing to do with my initial proposal ;)
This thread was not meant for debugging my performance issues - especially
since I already solved them last week. ^^ It is more or less just a 
reflection
of the fact, that the Performance Info was just very useless for actually
finding out infos about the performance.
