More benchmarks of Ubuntu 14.04 LTS on Amazon's EC2 are to come when the release is near finalized for this next Long Term Support release. These weekend benchmarks are just some preliminary figures I did for reference purposes in looking at the current "out of the box" performance between Ubuntu 12.04 LTS and Ubuntu 14.04 LTS as of this week on Amazon EC2.
The Amazon EC2 c3.2xlarge instance type was used for both Ubuntu LTS releases and the stock kernels/compilers/settings were tested on each platform.
Those wishing to see the early results can find all of the data hosted at OpenBenchmarking.org. Again, more results will be forthcoming. If you're interested in Amazon EC2 benchmarks, you can also checkout our recent benchmarking of the new C3 instance types and 5-way EC2 OS comparison.
