A better question is how long the COM TLD takes to transfer.  My guess is
that they don't use zone transfer for it, but instead use FTP or SCP to
transfer the compressed com.zone.gz file.  A few years ago, when the
com.zone.gz file was still in the above directory, it took me a couple of
hours to download it, so I figure downloading the uncompressed file would
have taken the better part of a day, and a zone transfer would be similar
(perhaps only half as long, since there's lots of whitespace in the file,
zone transfers just transfer the names and binary data for the other
fields).
