Note that prove unfortunately serializes the test output to be in the order it
started them, even when tests run concurrently. Extremely unhelpful, but ...

Isn't this kind of a good test time? I thought earlier your alltaptests target
took a good bit longer?

One nice bit is that the output is a *lot* easier to read.


You could try improving the total time by having prove remember slow tests and
use that file to run the slowest tests first next time. --state slow,save or
such I believe. Of course we'd have to save that state file...

To verify that tests actually run concurrently you could emit a few
notes. Looks like those are output immediately...

Greetings,

Andres Freund
