G1 status in JDK1.6 Vs JDK1.7

[Bharath R]

Hi,


Is the G1 GC 1.6 port on par with the 1.7 in terms of stability / quality? If that is true, I intend to begin experimenting with it in production and gradually roll it out across our deployment based on the outcome. On a related note, we intend to use G1 for an online system with a very low pause time requirement ( <10ms). The hardware is heterogeneous in terms of memory (ranges between 12G - 32G available to the application process) with comparable CPU configuration. CMS required considerable tuning to achieve acceptable results and I'm hoping G1 would fare better without myraid config options or overrides. 

I'd like to know of comparisons / experience operating G1 in production under such conditions. Thanks in advance.

P.S: Using RTJ is not an option for us :)
