[osmosis-dev] Osmosis --apply-change vs --merge-change performance

[Brett Henderson]

I suspect the first version should be quicker due to processing the full
planet in an --apply-change task only once.

But in practice it may not make much difference.  The overheads of an extra
entity comparison may not be much compared to the rest of processing.
