after 10 seconds of typing inside 1 method 2-3 MB of Object[] (not counting 
other things) are created

77% of that is from within WorkingCopy.reconcile()

i do not know enough about that code to suggest any solutions here :-(

Parser is creating objects, but I suspect it isn't the only one. Bridging is 
probably costly too.

Closing, compiling is involving lots of object allocations (reconcile with 
errors is needing compile).
