As Zoe Slattery mentions in her new post more testing for PHP is a good thing, but has come with a bit of a problem.

One of the problems with the incredible level of success of the PHP TestFest is that PHP gets more tests, 887 more to be precise. Well, isn't that the point? Yes, but it's beginning to take *forever* to run them which is a bad thing and as TestFests get bigger and better this will only get worse.

As a result, more work has been put into a project started a while back - a tool to allow more than one test to run at once (instead of linearly). This grab shows some of the resulting gains in speed. It jumps to about half to the time to make it through the ~7700 tests.
