+# High Latency TCP Might Be Caused By TCP No Delay
+https://brooker.co.za/blog/2024/05/09/nagle.html
+
+Describes a situation where two algorithms in TCP bite each other:
+- Nagle's algorithm tries to prevent sending very small data packets to minimze header overhead
+- Delayed ACK delays acks until data's ready
+
+So the first holds packets back until an ACK is received, the second holds ACK until the response is ready.
+
+Also due to modern systems the penalty for small datagrams is much lower.
+
+To get rid of Nagle's algorithm when latency matters: enable TCP_NODELAY.
