Is there any drawback of setting the capacity of sender to very high

[Rajesh Khan <ra...@gmail.com>]

I wanted to know what side affects would there be other than greater
consumption of memory on the sender if we set the capacity of the sender to
say 8000 and the receiver capacity to also 8000 and acknowledge after every
7200 messages. I will be receiving about 8 messages every millisecond. Is
there another side of the picture that I am not considering ?

Generally performance is a little better with slightly smaller 
capacities on both sender and receiver. You want it large enough to 
prevent stalling on a round trip, generally I find a few hundred is as 
high as you need to go.
