I note that the PK for this table is a BIGINT, is that true for your other tables?

Do the rows in this table undergo a lot of activity which would create record versions? If so, what do the database header page statistics look like? An uncommitted transaction, combined with a lot of updates could result in slow query as the system would need to walk the version list to get the latest version.
