Default PHOTOPRISM_INDEX_WORKERS is NumCPU/2 (3 on the M0 6-core test LXC). Each worker forks TF + ffmpeg + libvips, so a fresh index of ~1.2k photos pushed the LXC's load avg above 50 and starved the Proxmox host. Pin to PP_WORKERS / PP_INDEX_WORKERS (default 2) so the indexer is calm by default; bump in .env.photoprism on dedicated boxes.
