Vercel says median snapshot creation time in Sandbox has fallen from 4.4 seconds to under 0.4 seconds. Median restore time has improved by 50%, from 500ms to 250ms.

The update reuses frames within Vercel's snapshot format and indexes data to allow more parallel reads and writes. Persistent sandboxes automatically save a snapshot when a session stops and resume from the latest one.

The changes apply to all new snapshots without configuration. Existing snapshots retain the previous format.
