No, the comparison is only using checksums.

Are you always mounting on the same computer using the same --cachedir?
If not, S3QL will always have to download an up to date copy of the
metadata.
If not, my best guess is that some other program is reading data from
the mounted filesystem (maybe some indexer?).
Does AWS give you more detailed logs? It would be interesting to know
which objects are being downloaded.
Best,
