Impact of GOAMD64 on simdjson-go #69

Closed rabbbit closed 2 years ago

rabbbit commented 2 years ago

Hi!

Go 1.18 added the GOAMD64 build environment variable (https://tip.golang.org/doc/go1.18#amd64, https://github.com/golang/go/wiki/MinimumRequirements#amd64).

On the surface, it would seem that GOAMD64=v3+ should affect performance of this package, since it's adding a bunch of SIMD instructions.

Could you please verify that assumption? Is there any relationship between the environmental variable and this project?

Thanks,

Parsing requires v3. Features are detected runtime, so the flags doesn't do anything.

(and it there is no real benefit from it)
