What are some real world values, best practices, and concerns regarding rate limits for DAI, storm control, and DHCP?

I have found the same thing, and apply a burst interval of 10 seconds to each port like such:

ip arp inspection limit rate 15 burst interval 10

During some testing I found that a 3750 could handle 3000 ARP packets per second during inspection and not keel over.

I don't tweak any of the DHCP snooping limits or anything.
