I don’t see this behavior at all on my system. After discarding an intial compilation step, here’s what I get:
0.3 — elapsed time: 3.013803287 seconds (400120776 bytes allocated, 1.77% gc time) 0.4 — elapsed time: 2.920384195 seconds (400120776 bytes allocated, 1.89% gc time) Also to clarify: do you mean to refer to 0.3 as a regression relative 0.4? — John On Aug 22, 2014, at 9:50 PM, Don MacMillen <[email protected]> wrote: > Is anyone else seeing the following?
