Vlad Krasnov from Cloudflare has an excellent blog post up about performance on Qualcomm's new Centriq 2400. In it he discusses several deficiencies in Go's arm64 support that show up in performance numbers that are both less than anticipated and easily improved.
https://blog.cloudflare.com/arm-takes-wing/ "Go support for aarch64 is quite disappointing. I am very happy to say that everything compiles and works flawlessly, but on the performance side, things should get better. Is seems like the enablement effort so far was concentrated on the compiler back end, and the library was left largely untouched. There are a lot of low hanging optimization fruits out there, like my 20 minute fix for addMulVVW clearly shows. Qualcomm and other ARMv8 vendors intends to put significant engineering resources to amend this situation, but really any one can contribute to Go. So if you want to live your mark, now is the time." thanks Ed -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
