On Node, a server socket keeps Nagle's algorithm enabled. A frame written as more than one small packet then waits for the client's delayed ACK. On Linux that adds about 40 ms to each reply. Bun's sockets are not affected. Call setNoDelay(true) on each accepted ssh2 connection, after the close and error handlers are registered, so a failure is reported through the normal cleanup path. Loopback ssh2 probe, two small writes per reply, client with TCP_NODELAY (as interactive OpenSSH sets it), median of 60 replies: node 26.4 off 41.011 ms on 0.107 ms node 26.7 off 41.003 ms on 0.106 ms bun 1.4 off 0.048 ms on 0.045 ms
