I was doing some timing tests and happened to have multiple versions of OpenSCAD open on my test file. I normally develop in the stable version 2019.05, but I also had 2020.07.23.ai5587 (git 4dcd5a9) with and without function literals enabled and 2019.12.21.ai4163 (git 4ef45b0). I was doing this timing test: function subindex(v, idx) = [ for(val=v) let( value=[for(i=idx) val[i]] ) len(value)==1 ? value[0] : value ]; M = [[3,4],[2,1]]; N=500000; foo = [for(i=[0:N]) subindex(M,1)]; And each version took a different reported time, with 2019.05 taking 4s, 2019.12 taking 6s, and 2020.07 taking 7.6s. I can clearly see that they finish at different times. Is this a real change in performance? Or are the nightly builds compiled with less optimization or something? I'm running AppImage versions under Linux. -- Sent from: http://forum.openscad.org/
