Omera is built for large libraries. The gallery renders from the indexed SQLite database before any filesystem reconciliation begins — no blocking startup scan.
| Metric | 1 k images | 10 k images | 50 k images |
|---|---|---|---|
| Time to first usable gallery (warm DB) | 4.48 ms | 23.65 ms | 143.55 ms |
| Main-thread long tasks (> 50 ms) during rapid scrollbar drag | 0 | 0 | 0 |
| Thumbnail manifest adoption | — | — | 3.26 s (15,300 files/sec) |
Additional safeguards:
- O(1) Keyset Cursor Pagination — < 1 ms per page at 500 k+ assets (84× faster than
OFFSET). - Frame-Coalesced Scrolling — At most 1 reactive update per
requestAnimationFrame. - Per-Column Binary Search — Waterfall visibility computed via binary search, not full-library scan.
- Demand-Driven Thumbnails — Visible images decoded first; look-ahead starts only after scrolling settles.
- Directory Fingerprint Gating — Parent
mtimecheck delivers 2.5× local / 5.6× network speedup on re-scans.
