      Compaction already checks how eviction is doing with __wt_cache_eviction_check. However, it does not check if the cache is operating aggressively, which could be a good indicator of pressure on the system. It could be great to check the output of __wt_cache_aggressive periodically when background compaction is operating to make sure it does not add more load to the system at the wrong time.
