Vercel Sandbox Makes Snapshots 10x Faster

This is a meaningful infrastructure upgrade for agent workloads, where repeated stop-resume cycles can quietly add substantial latency.

• –VHS frame reuse enables parallel snapshot reads and writes
• –Faster restores make persistent sandboxes feel closer to continuous environments
• –AI coding agents can checkpoint and resume with less workflow friction
• –New snapshots receive the improvement automatically; existing snapshots retain the old format
• –Vercel reports median performance, so tail latency remains an open question
