Yep, that should pretty much be the case (should...)

The problem in Lazarus (at  least SynEdit, but probably others too) is a 
lot of memory constantly freed and released. also SynEdit allocates 
tenthousands of small bits (e.g a string per line).

It's a dream of mine to optimize that. eg. to have synedit allocate a 
bigger chunk, and have synedit use it knowlege about lifetime of data, 
to organize it better.  But there is just to much other important work...
