---------------------------------------

[~ram_krish] Yeah... 0.98, sorry. Good catch :)
Most should translate to trunk, but some things will be different.

> I ran HBase with "-XX:+PrintCompilation -XX:+UnlockDiagnosticVMOptions -XX:+PrintInlining"
and then looked for "hot method too big" log lines.
> I'll attach a log of those messages.
> I tried to increase -XX:FreqInlineSize to 1010 to inline all these methods (as long as
they're hot, but actually didn't see any improvement).
> In all cases I primed the JVM to make sure the JVM gets a chance to profile the methods
and decide whether they're hot or not.
