Have you tried the new G1 GC? I'm not very familiar with GC tuning, but I thought using the CMS GC with vary large heaps is asking for trouble. Apparently the G1 GC alleviates this, and still manages to be as "cool" as the CMS GC. |

IIRC, I did and it didn't benchmark well for my needs. However, it all depends on what JRE you're using and what the system is doing to pick the GC which is best for any given deployment. Classic case of YMMV and all that.
In the end, even though it may sound trite, the only way to know what works best for a given combination of JRE/OS/hardware is to measure it. This article[1] had some good tips and Mission Control[2] is a huge help in this arena.
