We have ignored the parsing and processing logic of packet because they are not relevant to the optimizations we are discussing. But buf deserves our attention: its default size is 4KB. This means that all connections will consume additional gigabytes of memory. "Writer" is a similar situation:
func (c *Channel) writer() { // We make buffered write to reduce write syscalls. buf := bufio.NewWriter(c.conn) for pkt := range c.send { _ :
system calls. In an infinite loop, we expect to receive new data. Remember the previous sentence: Expect to receive new data. We'll discuss that later.
