[go-nuts] Re: when has multi GOPATH, go can`t detect the vendor folder.

By "has a vendor folder in it's root dir" do you mean /workspace/specific/project/vendor? If so, go didn't find it because that directory is outside of /workspace/specific/project/src/, and thus not seen as source files in the GOPATH. It works when the project is under /go because the vendor

Hi Remy, It turns out that you are at least partially on the right track :-) I changed the way Barrett is written, so as to use as few temporary variables as possible. In particular, the Rsh doesn't use any at all anymore ... the 60% of the Rsh time that was being used in runtime.mallocgc

One more bit of progress which shaved off more time: following this page, https://blog.golang.org/profiling-go-programs I introduced a pair of global cache big.Int variables for the function which was consuming most of the time; one for the smaller intermediate results and one for the

Re: [go-nuts] slow Mod function in math/big, a better way?

I managed to do quite a bit better (30% savings in execution time) proceeding along these lines. Finally I got to the point where runtime.makeslice, and underneath runtime.mallocgc, are responsible for 50% of the run time, with no other real hotspots. Almost all of the makeslice time is

the example you have given is incomplete, but the most likely reason you're not being successful is that you are not setting correctly headers for multipart/mixed mime types. i've created a full working example here, hopefully this helps: https://play.golang.org/p/xVqUDN7OGt for more info on
