I have a fairly small go project (100k loc) and it takes ~30sec to build.

I'd be thrilled to have it build in 300ms.

That's strange. Humongous k8s Go projects (>500k LOC) build in a third of that time. Do you have lots of deps in your `go.mod` ? Is the project abusing codegen ?

61 dependencies, no codegen. Nothing special really.

On a Macbook M2 Pro, on a project with loads of services, 210k loc, a full rebuild takes 70 seconds. Incremental takes 36s. For one service, full rebuild in 16s and incremental 0.6s. It's not blazing fast but considering the scale of the project, it's not that bad, especially since I rarely rebuild every service at the same time.

Consider upgrading your hardware if/when you get a chance to (obviously this is expensive). My builds (Rust not Go, but it might well be similar?) got 10x faster when I upgraded from a 2015 MBP to an M1. I suspect 2019 to M4 might be similar.

Wait, aren't Go builds supposed to be fast?

Are you using CGo? C compilation slowness doesn't count.
