AEM 6.1 will have daily job scheduled and that will perform the Online Compaction.

Some times this may cause performance issue when the online compaction takes more time to complete due to load or authoring.

As a solution the online compaction job can be disabled and offline compaction can be used whenever required based on the maintenance window.

•  Go to CRXDE path - /libs/granite/operations/config/maintenance/granite:daily/granite:RevisionGC

• Changed run mode from crx3 to crx3-disabled

• Save
