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

Did you try running a recent (1.22.x) release? Did you check whether the
system might be under heavy GC?
Best regards, Julian
