The Release Automation environment's performance slows dramatically due to a large volume of archive logs being written to the database.
Version 4.7.1 introduced the periodic purging of health check records that generate two queries:
update health_round_samples_aud set REV = :1 where REV < :2
update health_sample_aud set REV = :1 where REV < :2
If the queries for this check run too often, it can impact performance.
