resp.Write() emits many small writes (status line, headers, body chunks). On a TLS connection each write becomes a separate encryption and write() syscall. Wrapping with an 8 KB bufio.Writer coalesces these into fewer, larger TLS records. Applied to both the HTTP handler and the MITM sniffer write paths.
