Does anyone know of compile-time benchmarks spanning 1.4 through 1.9, along the lines of [1]?

I see there's (more) parallel compilation in 1.9 - so that should improve elapsed time (but not reduce cpu time) of compilation.

Would be nice to know if 1.9 is (still) on track catch up to/pass 1.4.

I was curious so I downloaded Go 1.4, and tested against 1.9 on an old version of a project I have (backend for Mafia Watch), about 30K lines of Go, including a few 3rd party dependencies.

Go 1.4: Around 2.1s Go 1.9: Around 2.5s

So within 20% of 1.4, not bad. That's on an old MacBook Air, dual core 1.7 GHz i7, 8GB ram.

And of course the binary performance and GC pause times w/ 1.9 will be much better.

Here's the raw times: https://pastebin.com/ULDHPmVu

Two awesome things:

It was super-easy and fast to download and compile Go 1.4

It was completely painless to compile my old code with Go 1.9

I fucking love how nice it is to work with the Go ecosystem. <3

Dave posted one about halfway through the release cycle, showing a small improvement. That was before the parallel-function compilation though, so things might have gotten better since then.
