Testing for kernel performance regressions

The Phoronix test suite is also open source from what the page indicates. Which means that people can provide patches, fork etc.

Just wanted to point out that Phoronix has been a great resource for exactly the kind of benchmarking between kernel releases that the article was referring to, and has been doing so for years.

I wonder if any kernel developers have used the Phoronix results to help target fixes for various regressions.
