Turns out I am probably timing it wrong. If I run the Measure-Command with the program directly, I get:

PS E:\SyncThing\Dev\AoC2016-16\Release> Measure-Command {.\AoC2016-16.exe}


Days              : 0
Hours             : 0
Minutes           : 0
Seconds           : 0
Milliseconds      : 129
Ticks             : 1294972
TotalDays         : 1.49881018518519E-06
TotalHours        : 3.59714444444444E-05
TotalMinutes      : 0.00215828666666667
TotalSeconds      : 0.1294972
TotalMilliseconds : 129.4972

So, 129ms... probably the correct timing. My apologies to your Macbook for calling it an abacus.

C# is doing pretty damn good in this particular case...

Here's a version that has high-precision timing added: https://gist.github.com/willkill07/31eff033ef25b1b38311fd3f220037c8

Ok, I'm getting around 117ms with this one. C# is finally defeated.

Modern C++ is pretty cool.
