After upgrading VSAN 5.5 to VSAN 6.0 I thought it would be a good idea to run the same set of tests that I ran previously (VSAN 5.5 Performance Testing) to see how much of a performance increase we could expect.
The test was run using the same IOAnalyser VMs and test configuration, on the same hardware. The only different was the vCenter/ESXi/VSAN version.

VSAN 6 IOPs (Sum) 113,169.88 28,552.85 38,658.47
VSAN 5 IOPs (Sum) 61,964.81 5,666.06 24,228.98
The detailed test results for VSAN 6, using a “Real World” test pattern (70% Random / 80% Read) as below:
Great increase in IOPs!
