[go-nuts] Re: Did you try 1.7RC1 ?

I cannot wait for Go 1.7 to land in AppEngine! After AppEngine switched to 1.6 (from 1.4), the compilation speed have slowed down significantly. And this definitely reflects in our dev habits (more flipping over to HN while we wait for the recompilation to happen.) Hopefully, the 1.7 updates

Cheers, I tried replicating my endeavours (https://play.golang.org/p/Qxoo2ASac6), sorry if it's still too verbose. It's essentially rewriting the inbuilt ast.Node into a simpler nested struct and then walking it. In testing the performance, I started adding algebraic expressions, which make

Hello, I am trying to analyze why I am getting low throughput for my app. Below is the 30 second CPU profile output. I would expect more time spent in net/http serve. Not sure if runtime.mcall and runtime.schedule taking almost 1/4th of the time is concerning. When I did a "web mcall" it

Hello Val, Thanks for your thoughts. Indeed, for single user goroutine, I think your list is more or less ok. I can reliably reproduce single goroutine performance results in my code and it is in line with your list. (rand.Seed is not necessary b/c there is a default seed of 1). There was a

Hello Scott Determinism for runtime, not just builds, looks like a nice feature to have for some problems including yours. Sadly I don't have the solution, but it would be great to make 2 lists of how to achieve deterministic/reproducible executions in go : *Sequential programs* (only 1 user

Hi TL, It's identical between the two runs as best as can be with a rebuild in between two runs. The values used are the same. I'm going to dig into the assembly a bit when I get the time. For now the solution is to explicitly make copies, which was the desired result in the first place. The
