During the JVM Summit, I was doing some tests for
my presentation with the latest
when I've seen some *BIG* performance improvement between jdk7 b71 and jdk7 b72.
A quick look to the summary of changes, hum,
Escape Analysis is now enabled by default.
On my tests, I got a 3x improvement, Wow !
With a quick micro-benchmark, it's even better, as always :)
