# Vercel Flags冷启动提速7倍，响应后不再占用函数时长

Vercel宣布Flags SDK冷启动初始化速度提升7倍，且用量上报不再在响应返回后继续占用函数运行时间。提速来自两项改动：SDK直接加载并解析随部署打包的flags数据文件，省去额外网络请求。此前用量上报会在响应发出后继续运行函数，现在该行为已取消。对开发者而言，使用Vercel Flags的功能开关延迟更低，函数计费时长也不再被后台上报任务拖长。

## English Version

**Vercel Flags SDK Starts 7x Faster, Stops Extending Function Duration**

Vercel announced that its Flags SDK now initializes 7x faster on cold starts, and usage reporting no longer keeps functions running after the response is sent. The speedup comes from two changes: the SDK loads and parses the flags datafile bundled with the deployment directly, eliminating extra network requests. Previously, usage reporting continued running functions after responses were sent; that behavior is now removed. For developers, feature flags via Vercel Flags have lower latency, and billed function duration is no longer extended by background reporting tasks.
