sort bench
The small benchmark program shows the performance of std.algorithm.sort
compared to a different one (it doesn't accept a key sort function, etc).
One output example:
sort-sort2 benchmarks (milliseconds), N=6000000:
Random distribution:
sort: 4131
sort2: 2635
Already sorted arrays:
sort: 1979
sort2: 787
Inverted order arrays:
sort: 2105
sort2: 1374
Few random doubles appended to the sorted arrays:
sort: 2890
sort2: 1551
