When initializing a diagram from a model for my custom metamodel
("Initialize xyz_diagram diagram file"), depending on the model's size,
i get following runtime behavior:

<=2^7 model elements: 1 seconds diagram creation or loading time.

2^9 model elements: 3 seconds diagram creation or loading time.

2^11 model elements: 30 seconds diagram creation or loading time.

2^13 model elements: >10 minutes diagram creation or loading time.

For the last test (2^13), the time after clicking on "Initialize
xyz_diagram diagram file" to the point of time the wizard pop ups was 4
minutes (i guess because the model xml file is parsed (~4mb size)).

So it is not linear (linear would mean an increasement by factor 4 for
each step of this sequence).

Anyone an idea where the bottleneck could be?

I use GMF2 /Eclipse 3.3.0. I first tried profiling with tptp, but it
only supports up to 3.2.0 for profiling eclipse runtimes. Anyone has
another profiling tool? I am interested in method counting, since this
would be the hint where it starts getting not linear.

Thanks

Sorry I mean 3.2.2.

And it gets to an exception when clicking "Profile" and choosing a
eclipse runtime configuration (there is a problem with the tabs).
