We are using tar offline compaction on AEM 6.1 with oak-run1.2.25.jar and datastore size is 25-30GB
java -Xmx16G -jar oak-run1.2.25.jar checkpoints segmentstore
java -Xmx16G -jar oak-run1.2.25.jar checkpoints segmentstore rm-unreferenced
java -Xmx16G -Dtar.memoryMapped=true -Dupdate.limit=5000000 -Dcompress-interval=10000000 -Dcompaction-progress-log=1500000 -Dlogback.configurationFile=compactionLog.xml oak-run1.2.25.jar compact segmentstore
Average time for compaction is 3-4 hours but some times it take very long time upto 7-8 hours to finish which in result unavailable author server for users.
I have followed adobe recommendation to increase performance of offline.

Does anyone have other idea for this issue ?
