Check for long running queries on the server that is taking longer. If
it's things like CREATE INDEX or ALTER TABLE statements that are being
blocked, a transaction running on the table involved will cause those
commands to be held until those transactions complete.
If
it's normal read/write queries to that are taking longer, ensure the
database statistics are up to date by running an analyze.
