Toni,

3KB. Worst case 10KB.

Only when typing, moving around with the cursor, editing, cutting and  
pasting.
Actually the mouse hover features, like putting the mouse over a C function 
for help on that function has a pretty good response time of appox. < 0.5 
sec.

> Is there any background processing going on (Check the Progress view)?
checked the progress view. no.

40M of 231M

I can see however, doing a "top" in a console that java is eating the largest 
amount of processing power, but that is only ~5%, every few seconds.
