「第三個因素——可能與語言學習經驗一樣重要——是記憶容量，」雷布夏特告訴我。「與只使用單獨偽詞的中文研究不同，葡萄牙語的跨情境學習（CSL）任務要求你在腦中處理並記住整句語句（包括限定詞、名詞、動詞、數量標記），同時將它們與兩個動畫場景進行比對。這對短期記憶、順序處理與提取能力造成相當大的負荷。」

Git packfiles use delta compression, storing only the diff when a 10MB file changes by one line, while the objects table stores each version in full. A file modified 100 times takes about 1GB in Postgres versus maybe 50MB in a packfile. Postgres does TOAST and compress large values, but that’s compressing individual objects in isolation, not delta-compressing across versions the way packfiles do, so the storage overhead is real. A delta-compression layer that periodically repacks objects within Postgres, or offloads large blobs to S3 the way LFS does, is a natural next step. For most repositories it still won’t matter since the median repo is small and disk is cheap, and GitHub’s Spokes system made a similar trade-off years ago, storing three full uncompressed copies of every repository across data centres because redundancy and operational simplicity beat storage efficiency even at hundreds of exabytes.
