For those current users of Ubuntu 12.04 LTS curious about how the performance of Ubuntu 14.04 LTS will be if upgrading, I've been in the process of running some preview benchmarks to share the current situation of the Trusty Tahr in its present development form. Some early results to share this weekend run a few OpenGL benchmarks while comparing the state of Ubuntu 12.04.3 to Ubuntu 14.04 right now when using Intel "Ivy Bridge" HD Graphics 4000.
After the earlier small, low-power Linux PC testing
I ran some early comparative tests of Ubuntu 12.04.3 LTS against Ubuntu 14.04 with its current daily ISO as of today. Plenty more 12.04 vs. 14.04 LTS tests will be coming (and with 13.10 too) from a mixture of hardware and benchmarking various subsystems, but these results are just to satisfy anyone's curiosity this weekend.
The system details and other early few results are on OpenBenchmarking.org via 1401257-PL-INTELUBUN79
