Deployment speed improved by up to 7 seconds

Over the past few months, Vercel has improved end-to-end deployment speed by up to 7 seconds. Platform overhead has been reduced by up to 5 seconds, and using the latest Vercel CLI can save up to an additional 2 seconds. These improvements are more noticeable for smaller builds, where orchestration accounts for a larger share of the total build time.

Key platform improvements include:

• ~2.2s: Moved internal build process shutdown work outside the critical path for deployment readiness
• ~930ms: Reduced startup time by pre-warming the Vercel CLI within the isolated build environment
• ~413ms: Processed routing and output metadata in parallel with other tasks to bring forward the deployment completion point
• ~900ms: Eliminated duplicate API and storage requests, and optimized build configuration and record loading

Using the latest CLI provides the following additional benefits:

• ~1s: Completes immediately when the event stream reports domain alias assignment, instead of waiting on polling
• ~650ms: Checks the deployment team directly instead of loading the full team list
• ~500ms: Reuses already-returned project information to avoid additional API requests
