(co-written with @neild) Linux has recvmmsg to read multiple UDP packets from the kernel at once. There is no Recvmmsg wrapper func in golang.org/x/sys/unix. That's easy enough to add, but it&#...

Obscure Go Optimisations - Bryan Boreham
Did you know that Go will sometimes embed a type-conversion silently into your program? And that conversion, especially if it requires a memory allocation, may be slowing things down by 20% or more? Come with us as Bryan shows how to look for these issues…
One more nice #golang JSON patch and 5% speed up. Sometimes it's enough just to read the code and remove a few lines.
