[ENet-discuss] Reliable packets and data sending approaches

[Lee Salzman]

Don't rely on the throttle. Choose a reasonable rate to begin with. 
20-30 times a second is probably fair. Keep in mind that on average an 
event will occur half-way between an interval, so 20 Hz does not 
correspond to 50 ms latency, but rather on average more like 25 ms, and 
by the time you get to 30 Hz your average latency is like 16 ms. Taking 
that up to 50 Hz, and your average latency is only about 10 ms, so 
you're making huge jumps in bandwidth usage for very marginal benefits.
