I ran the comparison again on another machine that I have and this time their performances are about the same:

c++:

    $ time ./tinykaboom
    ./tinykaboom  46.72s user 0.01s system 364% cpu 12.804 total

    $ time ./tinykaboom     
    ./tinykaboom  42.50s user 0.07s system 350% cpu 12.161 total

    $ time ./tinykaboom 
    ./tinykaboom  78.08s user 0.02s system 369% cpu 21.159 total

    $ go build ./tinykaboom.go
    $ time ./tinykaboom 
    ./tinykaboom  34.32s user 0.03s system 368% cpu 9.315 total

Here's the corresponding perf report:

Use numbers for dealing with files in git.

    DEFUN ("atan", Fatan, Satan, 1, 2, 0,

One look at any of the assembly files and you can get a sense of how properly organized the source code is.

I pray that I won’t ever need to consider taking it though (passed one stone last year)
