[Mono-dev] Need Help on Commons.Xml.Relaxng.dll

[Atsushi Eno]

You said you run the examples on the web page you mentioned earlier, right?
Which code did you run? How did you confirm profiling numbers? How much 
was the memory consumption? There should be exact information here and 
there.

Commons.Xml.Relaxng.Derivative objects are created a lot, and lots of 
them are linked to the same objects so they don't consume more memory. 
You won't be able to see that if you're just looking at VS debugger though.
