I don't know if there are stats available, but the requests per second has got to be huge.
There are a ton of ISPs, and many of them run regional recursive servers. Each of those servers is going to see a ton of different domains that they need to query at the registry servers. Most registries are serving glue records with a 1-3 day TTL, but ISP caches may not have enough memory to keep the long tail names in cache for that long, and the long tail is long. There's millions of domain names to query the registry servers for.
