Hi

We have an AEM instance with about 700G of segment store.

I tried to run a full compaction on it with ‘oak-run-1.22.4.jar’ but that is 
very slow.

I gave the Java process 16G of memory, the disk space should be sufficient and 
use a logger on INFO to track the progress.

What I see is that it lists the compared nodes 150,000 at a time but that gets 
slower and slower and the completion remains at 0% even after 2h of running.

Is there a way to limit the compaction to less than FULL?

Any way to speed it up?


At the start of the compaction it reports:

- Estimated Number of Nodes to Compacted: 1,847,030,487
- Base on 3,918,808,571 nodes compared to 158,124,219,904 bytes on disk in 
previous compaction
- Current size of 745,415,686,656 bytes on disk

Cheers - Andy
