Phoronix: Ubuntu 12.04 LTS To Ubuntu 14.10 Offers Some Performance Improvements

Curious how the CPU performance of Ubuntu Linux has evolved from the 12.04 LTS release compared to 14.04 LTS and then the latest 14.10 release? Here's some benchmarks...

I suspect most of these gains can be realized by just running 12.04 with the newer "hardware enablement" kernels rather than a full on dist upgrade

Older LTS releases don't receive a newer compiler though, which benefited most of the CPU bound tests.

Actually, 12.04.5 and 14.04 are running the same 3.13 kernel in this test:

I'd be curious to see what performance was like with the original 3.2 kernel...

Older LTS releases don't receive a newer compiler though, which benefited most of the CPU bound tests.

But by installing Ubuntu's toolchain repo, later compiler versions can be made available on 12.04. I'm running GCC 4.9.2 on Ubuntu 12.04.5 with kernel 3.13 right now.

The instructions at http://ubuntuhandbook.org/index.php/...u-12-04-13-04/ are a bit out of date now, but still pretty accurate and informative.
