      Description

        Fusion Apps performance using G1 is lagging that of CMS.

        One reason we have found for this is the compilation of methods when using G1 -- CMS compiling more and inlining more methods than G1. We know that some G1 methods are larger because of the G1 write barrier, but even increasing InlineSmallCode has not helped with that problem (and in fact increasing it too large has made things worse).
