That is likely a consequence of the new Hardened-SHA1 algorithm used.

For most operations, Fossil does not use SHA1 that much, and so the
Hardened-SHA1, while slower, does not significantly impact
performance.  The test-integrity operation is an exception, though, in
that it computes a SHA1 for every artifact in the repository.
