Very nice screenshots. Is this some sort a debugger?

Assuming that you wrote both tcl and python versions and that they both wrap the same core library, wouldn't the call trees look the same or at least bear resemblance?

Yes, both the TCL and PYTHON extensions are wrappers for the same library and the TOOL for writing both wrappers is the NHI1/ALC (All-Language-Compiler), that is why both wrappers look similar.

  What I meant was that the two images look very different. I can't make out what the boxes say, but nevertheless one is wide and shallow, the other narrow and deep. So this may not be an apples-to-apples comparison. As has been noted already, shimmering may play a role here or extra levels of abstraction via extra proc calls may skew the results in one language vs. the other.
 

these two pictures are generated by the tool and not by me…
-> the TCL picture is so "wide" because the TCL uses a lot of "overhead"
-> the python picture is so "narrow" because PYTHON uses much less "overhead".
