Hi sun min,

It sounds like premature optimization to configure or tune the GC
algorithm at all.  The JVM (any version) will be able to configure
itself, even if perhaps not optimally, without setting either
"+UseParallelGC" or "+UseG1GC".  Is that all we need to change?

We should be able to build and ship the package with conservative
(compatible) defaults and document tuning for better performance in a
wiki or similar.

Cheers,
tony
