Hi there, Recently I run into this very interesting post: http://www.johnmyleswhite.com/notebook/2013/12/06/writing-type-stable-code-in-julia/
Surprisingly, when tested both examples against the latest 0.4 build - the speed difference of the type-stable version is only 2-3 times faster then unstable one. I wonder what is the source of such a huge disparity and what version of Julia was used? My timings: unstable: 0.425013212 seconds (305 MB allocated, 7.56% gc time in 14 pauses with 0 full sweep) stable: 0.14287404 seconds (896 bytes allocated) John's: unstable: 0.412261722 seconds (320002496 bytes allocated) stable: 0.008509995 seconds (896 bytes allocated) Thanks, kuba
