Our latest benchmarks of Ubuntu 14.04 LTS in its current development form come from testing it on Amazon's Elastic Compute Cloud.

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.
