I don't expect FPC behave much better. Whenever you move something from 
compile time to execution time you may gain in flexibility, but you 
surely lose in performance. Whenever a generic can be replaced by an if 
.. then .. else .., using a generic is just an useless performance killer.
The same holds true for using a TObject, when a record would be enough 
or for using an Interface instead of just linking the appropriate 
library when this would be possible (see Lazarus vs fpGui!).
