Please send me the config entries for them. Also, if anyone has used ZPT with 
it, let me know if my guess of the config for them is correct :)

No, there's still the performance check for "am I in debug mode?" which is 
equivalent to "am I in profiling mode?". Sure, it's small, but it's there.

Yep, I know :)

In the works already :)

I'll put a legend in. Is the colour coding what you meant by "clearer" or is 
there something else?

Yep, that's a good idea.

I've already got some more code in place that I'm testing right now which 
does aggregation of matching result profiles. That is, if a request results 
in the same call profile, the timings are aggregated into min/average/max. 
Really neat :)

Thanks for the feedback!
