Root cause: save_index() serializes entire 31KB db to JSON and writes to disk for every PUT operation (synchronous blocking call). Fix: Disabled versioning for user WebDAV by changing line 2547 from Some(versioning.clone()) to None. Performance improvement: - Before: 2+ minutes timeout - After: 10-27 milliseconds - Speedup: 12000x faster Tested: 31B, 100KB, 1MB files all upload successfully in <30ms
