Exceptional battery life: The new MacBook Pro gets up to 24 hours of battery life, giving Intel-based upgraders up to 13 additional hours, and users coming from M1 models will get up to three more hours, so they can get more done on a single charge.2 And unlike many PC laptops, MacBook Pro delivers the same incredible performance whether plugged in or on battery. Users will be able to fast-charge up to 50 percent in just 30 minutes using a 96W or higher USB-C power adapter.2

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.
