Packet Limiter
Drops attacks and swings that would go over a server's packet limit
Servers kick you for sending too many packets in a short time. Paper's default is 500 packets in 7 seconds. Every packet you send counts towards the limit, but only attacks, swings and clicks on entities are ever dropped, since losing movement, keep alives or inventory clicks would be worse than the kick. So the limit can still be passed by other packets alone, like a long Blink being sent all at once.
Window (s)
How many seconds packets are counted over.
Max packets
How many packets can go out within the window before attacks, swings and entity clicks start being dropped. Defaults to 450, a little under Paper's 500.
Limit attacks
Caps how many attacks go out each second, on top of the packet limit. On by default.
Max attacks per second
Attacks past this many in a second are dropped.
