Vercel Sandbox snapshot creation is now up to 10x faster
Vercel’s Sandbox snapshots now create and restore up to 10 times faster, reducing median creation time from 4.4 seconds to under 0.4 seconds and improving restore speed by 50%.
Vercel has announced that Sandbox snapshot creation is now up to 10 times faster, with the median time reduced from 4.4 seconds to under 0.4 seconds. The improvement stems from optimizations in the Vercel Hive Snapshot (VHS) format, which now indexes data more efficiently. This allows read and write operations to occur in parallel, accelerating both snapshot creation and restoration processes.
Snapshot restoration speed has also improved by 50%, dropping from 500 milliseconds to 250 milliseconds at the p50 percentile. The faster performance is achieved by reusing frames within the VHS format, enabling parallel processing of base images and user data during restoration. Persistent sandboxes, which are the default setting, automatically create and resume snapshots without requiring any configuration changes.
The update applies to all new snapshots, while existing snapshots retain the previous format. The changes are designed to enhance developer productivity by reducing wait times during snapshot operations. Vercel states that these improvements are part of ongoing efforts to optimize the Sandbox experience for users.
The announcement highlights Vercel’s focus on improving the efficiency of its development tools. By streamlining snapshot processes, the company aims to provide a more responsive and seamless workflow for developers working with Sandbox environments.
