Hi Martin,
I measured this with the same executable (so I did not recompile the
project), using mark scan garbage collector. I did not measure the
difference using the heap profiler, but using the information in the console
with stack trace on. I will send you the executable, so you can see the
difference...
greetings,
Paul
