Vercel prewarms build containers, dropping Secure Compute and Static IP build start from 6.7s to 2.4s
Vercel Changelog·low signal
Vercel changed how Secure Compute and Static IP builds start: instead of booting a fresh container and then configuring the network, it now attaches network configuration to a prewarmed container at build start. Average time from deployment creation to build start fell from 6.7 seconds to 2.4 seconds, a 64% reduction. It applies automatically with no configuration change for teams on either feature.
