Well, TLD servers get much more (legitimate) queries than the roots
Define "much more". What do you mean, absolute numbers of queries or relative compared to the total query load?
Absolute number of queries that are made because a client legitimately doesn't know something and wants to find out. Now obviously for the roots this number is fairly insignificant as I gather that 98% of all queries are done for different reasons. But we don't really care much whether those don't work, do we?
Do you have data to back up this claim?
Just common sense.
because there is only so much you can ask the roots before the entire
root zone is in your cache. This is slightly harder with .com, for
instance. :-)
The contents of a cache depends of the query pattern of the clients, not on the size of a zone.
The sizes of the zones for the root and .com are somewhere in the order of 100 and 10 million, respectively. So even if someone is interested in ALL the information in the root, the number of queries to the .com servers will be higher if that same person is interested in more than a thousandth of a percent of the information in the .com zone. I believe this to be true for most user populations.
