IMHO it is not useful to look at the tx-ring in isolation. When a network is
designed for a given end to end latency, the fixed and variable latencies
should be within the goal, be it 150 msec for voice or whatever the network
is designed for.
IOS self tuines the tx-ring size to 2 for links less than 2 Mbits, 4 for
links less than 10 Meg, 8 for links less than 20 Meg and so on. It is only
worth tuning the tx-ring to less than the default, when the default does not
meet the end to end design goal (and don't tune to less than 2). It is good
practice to leave the tx-ring at the highest value that will still meet
delay requirements as that helps the interface to maintain line rate
transmission under a broader range of offered load conditions.
