16. What RWIN (TCP Receive Window) value should I use ?
The TCP Receive Window (RWIN) value depends on two main factors:
There is a BDP (bandwidth * delay product) formula that gives the approximate RWIN you should use for a given throughput and latency...
The Analyzer and the Optimizer go a couple of steps further in optimizing RWIN:
After all those calculations, here is a very rough breakdown of the Analyzer recommended values... Assuming land lines (satellite should use larger RWIN values because of the high latency), and 1492 MTU:
