I don't have the exact numbers, of course, but given the time it takes to
scan a directory tree on ext2fs I'd suspect that scanning one directory
with, say, 100 entries 100 times a day would be much faster than scanning
1000 directories of those 100 entries everytime anything in the directory
tree is changed. The lsR would have to start at the tree root, and when
_any_ file is changed, it has to be regenerated _entirely_ which means
traversing _all_ directories. If, OTOH, a client asks for a listing of one
directory only that directory is scanned. In other words, the on-demand
approach is more "politically" correct since it does only the job that's
really needed.
