What's this?

I was curious about the difference of GNU yes.c and OpenBSD yes.c.

I implemented both variants in Go. Here's my fastest variant with around 8 GiB data throughput per second. For the sake of completeness, a simple for {} loop like this:

for {
    fmt.Println("y")
}

has a throughput of just 3-4 MiB per second.

How to use it

git clone https://github.com/mnlwldr/yes

Usage and output

go run Main.go | pv -r > /dev/null
[8,10GiB/s]

You can install pv from here.
