It’s going to be complex, it’s going to be brittle, it’s going to eventually break and I’d rather not have it sitting around broken inside the main source tree. The only way to find the regressions is going to be longitudinally testing and keeping track of numbers over time, so it’ll be quite a complex piece of work.<div class=""><br class=""></div><div class="">P<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On May 1, 2018, at 10:05 AM, Björn Harrtell <<a href="mailto:bjorn.harrtell@gmail.com" class="">bjorn.harrtell@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Hi devs,<div class=""><br class=""></div><div class="">In recent times I've been pondering on about how to make a sensible test suite specifically for performance.
