What do you mean by queue discipline?
- jeffbee 6y agoYou know, the worst part is that Linux sets the maximum receive window size at boot time depending on how much memory the system contains, ensuring that it's never quite right. On this machine, with 32GB of main memory, it defaults to 6291456 bytes.

- jeffbee 6y agoIf you face a choice of what frame to put on the wire at any moment, the queue discipline makes that choice. The easiest policy is to simply send the oldest frame, but this is also the worst policy.
