> 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.
