I did a fresh install of 16.10 on my Macbook Pro Retina mid-2012 (rMBP 10,1). It seems quite stable so far, and brings a bunch of small improvements over 16.04. Improved from 16.04 Startup Disk Creator can be used for creating the ISO Installer works more smoothly Nvidia drivers no longer required for good performance Intel power management works correctly Now for the directions! 1. Resize Partitions This step is pretty straight-forward.

I recently spent a bunch of time investigating why a Java application was spending a significant amount of time paused, even when garbage collection cycles were only taking ~200ms. The issue turned out to be other safepoints. For those that don’t know, the VM uses safepoints to perform a variety of internal operations, and they involve pausing every Java thread. Garbage collection is the most well known, but many other operations such as deoptimization, and revoking biased locks require a safepoint as well.
