-## ⚡ Performance Optimization (Optional)
-
-For larger databases (≈1–2 GB), you can significantly speed up backups by enabling
-parallel PostgreSQL dumps.
-
-### Parallel pg_dump
-
-Set the number of parallel jobs:
-
-```env
-PG_DUMP_JOBS=4
-```
-
-**Notes**
-- Only applies to `dump`, `custom`, or `tar` formats
-- Default is `1` (safe for all users)
-- Recommended values: `2–4`
-- Higher values may overload small databases
-
-This feature is **fully optional** and disabled by default.
