this makes no sense. it's the wrong tool for the job. you want to be using a sparse adjacency matrix to store your data, and then operate on it. will be orders of magnitude faster than this.
"Optimization, again. TCP is implemented in the kernel and, in part, in the network card. When using TCP we can make one call to the kernel to hand it a large buffer of data and say “segment and package this as you see fit”. When using UDP, because we have to do that segmenting and packaging ourselves, we hand each packet individually the kernel. Each call to the kernel is expensive and the overhead becomes very significant, especially in Go. The kernel’s TCP stack is also highly optimized for performance while the kernel’s UDP stack is typically not."
