Hi, Has anyone got any experience of high performance image processing in go?
By this I mean doing complex image processing in real time at 4K resolution on commodity hardware. This is really pushing it using carefully written C++ but when we tried writing similar code using go slices we go a significant slowdown (x4 over gcc). We experimented using unsafe pointers thinking it is go's slice range checking that cause the problems, but surprisingly saw no improvement. Has anyone had success saturating the memory bandwidth using go? Is my result a surprise to people? Is it just that gcc's code generator is very mature and Go's is less so, or should I keep looking for dropoffs in my code? I haven't looked at the generated assembly yet, but that is my next step. Any opinions? -Steve -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
