In most cases, RDM won't take up anywhere near 50% of the bandwidth. Most RDM packets are relatively short (under 80 bytes for the request plus response), so even if you're sending an RDM request between every NSC refresh it's still only a marginal impact on refresh rate. And most controllers don't send DMX at the maximum refresh rate anyway.

The few RDM packets that are longer than about 100 bytes aren't things you're likely to do during a show. They're primarily setup messages that you send one time when you're first patching the rig.

Some badly designed products will flicker when they see RDM traffic because they don't properly ignore non-zero startcodes. RDM discovery can also cause flicker under some conditions, so you may want avoid running discovery during shows.
