All those documented in http://cr.openjdk.java.net/~jrose/pres/indy-javadoc-mlvm/ .  That is the leading edge of the JSR 292 Expert Group's work.

Microbenchmarks have little or no value even for mature frameworks.  For JSR 292, the framework is new and buggy.  In any case, we are not working on performance tuning yet.
