I'm happy to announce a release of tasty-bench-0.2.5.
It is a featherlight benchmark framework with API mimicking criterion and gauge.
* It supports GHCs from 7.0 to 9.2 alpha.
Running benchmarks on a bleeding edge GHC is important to identify
potential performance degradation before a compiler is released.
* A build on a clean machine is 16 times faster than criterion
and 4 times faster than gauge. A build without dependencies
is 6 times faster than criterion and 8 times faster than gauge.
One can build benchmarks on CI without wasting excessive resources.
* Benchmarks can be written together with tests, and can itself be
turned into a performance regression test suite.
In fact our benchmarks are just regular tasty tests.
* Comparisons between benchmarks are readily available out of the box:
no external tools (like criterion-compare or bench-show) are required.
One can compare results between runs and between individual benchmarks
instead of squinting at absolute numbers.
