Hello Laurent, Hmmm....
-Xincgc Enable the incremental garbage collector. The incremental garbage collector, which is off by default, will eliminate occasional garbage-collection pauses during program execution. However, it can lead to a roughly 10% decrease in overall GC performance From: http://java.sun.com/products/hotspot/2.0/README.html#use If you can live with a 10% decrease in overall garbage collection performance, then yeah, I guess use incremental garbage collection.
