ceroma c9cd59f443 Feature/improve performance of portfolio snapshot computation - 2 Continuing my perf analysis of the portfolio snapshot computation, this was another big time sink on my machine, specially when generating each day for the `'5y'` and `'max'` date ranges. For reference, before this diff, the `dateRange` loop was taking on average ~100ms per symbol for me (Raspberry Pi 4, 478 symbols in the DB). After this diff, it takes ~15ms per symbol, shaving off 40s of computation time. Test Plan: Check that result of portfolio snapshot computation is the same before and after this diff: 1. Flush portfolio snapshot cache: ``` $ docker exec -it ghostfolio-redis-1 redis-cli --pass $REDIS_PASSWORD del "portfolio-snapshot-f9e4c63e-4b8e-46fc-b6ed-75ca0205f12b" ``` 2. Open Accounts to trigger snapshot calculation 3. Dump portfolio snapshot to a file: ``` $ docker exec -it ghostfolio-redis-1 redis-cli --pass $REDIS_PASSWORD --no-auth-warning get "portfolio-snapshot-f9e4c63e-4b8e-46fc-b6ed-75ca0205f12b" \| python -c "import json, sys; json.dump(json.loads(json.loads(json.load(sys.stdin))), sys.stdout, indent=2, sort_keys=True)" > snapshot-before.json ``` 4. Apply this patch 5. Repeat steps 1-3 6. Compare results, check everything matches except for expiration time: ``` $ diff snapshot-before.json snapshot-after.json 2c2 < "expiration": 1727449402720, --- > "expiration": 1727449639794, ```		1 year ago
