Hi Phil, As I understand you have disabled the MLS rate-limiter for redirects, so that should not cause throttling, but you can check with "sh ibc" to see the rate at which packets arrive to the CPU.
With mls rate-limit redirect disabled, packets will be still subject to CoPP because they require CPU processing to generate a redirect, so perhaps your CoPP policy (probably class default) is limiting them? That can also cause packet loss between those stations if the traffic requires punting. You could also check the "ip icmp rate-limit unreachable" command, might be applicable here too.
