[Opensim-dev] Profiler installed on osgrid plazas server and profiler dump now available

[Impalah]

Questions...

The test was on a grid or standalone opensim?

And the memory increases where? In opensim.exe, assetserver.exe...?

(Yes, noob questions, it's only for identifying the "guilty" application).
