This section will measure the performance of WCbuffered.go and WCshared.go using the handy time(1) utility. However, this time, instead of presenting a graph, I will give you the actual output of the time(1) utility:
$ time go run WCshared.go /tmp/*.data /tmp/*.data real 0m31.836s user 0m31.659s sys 0m0.165s $ time go run WCbuffered.go /tmp/*.data /tmp/*.data real 0m31.823s user 0m31.656s sys 0m0.171s
As you can see, both utilities performed equally well, or equally badly if you prefer! However, apart from the speed of a program, what also matters is the clarity of its design and how easy it is to make code changes to it! Additionally, the presented way also times the compile times of both utilities, which might make the ...
