+1 non-binding Ran a performance comparison of 2.6.0 Latest with 2.7.0 RC, looks good, no regressions observed, most metrics are well within 5% tolerance (dfsio, sort, amrestart, gmv3) and some tests (scan, amscale, compression, shuffle) appear to have improvements.
Disclaimer, please note a JDK difference, 2.6.0 ran with jdk1.7 while 2.7.0 had jdk1.8, so some of the improvement may be from Java 1.8.0, that said, the 2.7.0 benchmarks compare well against current 2.6.0.
