Marc,

All Garbage Collection algorithms stop everything while marking
collectable objects. IBM has been way ahead of Sun in minimizing the
time that everything stops. Sun recently improved their garbage
collection support with 1.4.1 to be more on par with IBM and the
concurrent collector sounds closer to what IBM has been doing. A lot
depends on your hardware and application so you have to test to find out
what works best. Sun's defaults are way off for most applications I have
tuned and IBM and BEA's are generally closer.

JVMs on every Platform do GC in a seperate Thread and are of 
asynchronous nature, so its not very iSeries specific, or did i 
misunderstood something here?
