Appy commented on HBASE-15431:
------------------------------
I haven't done this kind of thing in past, so out of curiosity, i'd like to
know what were the things you did and where did you hit the wall. Can you
please enlighten us [~lhofhansl]. Thanks.
> A bunch of methods are hot and too big to be inlined

> Key: HBASE-15431
> URL: https://issues.apache.org/jira/browse/HBASE-15431
> Project: HBase
> Issue Type: Bug
> Reporter: Lars Hofhansl
> Attachments: hotMethods.txt
>
>
> 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.
