## Nagle’s algorithm and Delay ACK

- _small packets_ <span>&rarr;</span> not for TCP <span>&rarr;</span> Nagle algorithm: `Maximize ratio of packets - data content` <span>&rarr;</span> Delay ACK: `silly window`

```prolog
if available_data & window_size > MSS
	send payload on wire
else
	if unconfirmed_data
		queue
	else
		send
```
