I wanted to play with https://github.com/trustpath/sequence a little bit and was surprised to find that it took over a minute to compile on my computer (i7-6700K, 64GB RAM, Samsung SSD). Most of the programs I work on in Go are very fast to compile, and this is probably the only outlier I've ever noticed. At first I thought it must just be that the program was much more complicated than my usual project. But then I noticed that the compile times are wildly different with different versions of Go.
% docker run -it --rm golang:1.4 /bin/bash -c "go version ; time go get -u github.com/trustpath/sequence/cmd/sequence" go version go1.4.3 linux/amd64 real 0m11.227s user 0m4.493s sys 0m0.747s % docker run -it --rm golang:1.5 /bin/bash -c "go version ; time go get -u github.com/trustpath/sequence/cmd/sequence" go version go1.5.4 linux/amd64 real 0m11.812s user 0m7.930s sys 0m0.910s % docker run -it --rm golang:1.6 /bin/bash -c "go version ; time go get -u github.com/trustpath/sequence/cmd/sequence" go version go1.6.4 linux/amd64 real 0m12.258s user 0m8.063s sys 0m0.663s % docker run -it --rm golang:1.7 /bin/bash -c "go version ; time go get -u github.com/trustpath/sequence/cmd/sequence" go version go1.7.5 linux/amd64 real 1m26.425s user 1m21.607s sys 0m1.087s % docker run -it --rm golang:1.8 /bin/bash -c "go version ; time go get -u github.com/trustpath/sequence/cmd/sequence" go version go1.8rc3 linux/amd64 real 0m31.772s user 0m30.927s sys 0m1.117s (I realize that the build times above all include the time to fetch dependencies and whatnot). The compile times are pretty consistent on my computer. Build times are usually ~5 seconds faster without having to fetch dependencies. Like I said before, most of the Go programs I've compiled in the past are usually built within a few seconds at most. I'm not sure what about Go 1.7 and 1.8 could make such a huge difference in compile times. Any thoughts?
