Re: [go-nuts] Increase speed of repeated builds

[James Pettyjohn]

I tried using 1.7rc6, no issues in compilation but finishes only about half 
a second under 1.6.2.

I noticed that in the release notes, I'll try out the RC and see what it 
gives me.

1.7 should be much faster (the linker is about 3 times faster on some
things I tried).

[go-nuts] Increase speed of repeated builds

[James Pettyjohn]

I have a project which has become fairly large, I simple check of *.go, no 
_test files (including all modules), it's up to 1300 files. 

The main module though is 60 files, about 1MB of go source. It is taking to 
about 20 seconds to compile for a single change in the main module using go 
1.6.2 darwin/amd64.  

Using -x on go install I'm seeing half the time on build and half the time 
on linking.

I think I've gotten all the direct CGO dependencies moved to submodules but 
I'm not sure what would indicates if it is going through a cgo phase or not.

Any input on other things to look for or tune on what is making the build 
time so long?
