  You have optimized your frontend assets, implemented React Server Components, and cached your static content at the edge. Yet, your Vercel logs or Cloudflare analytics show a disturbing metric:   P99 latency hitting 2.5s+ on cold boots. If you are running a TypeScript backend on serverless infrastructure (AWS Lambda, Vercel Functions, or Cloudflare Workers) and using Prisma, the bottleneck is likely no longer your code or your database query speed—it is your ORM initialization. In 2025, the debate isn't about "Developer Experience" anymore; both ORMs are excellent there. The debate is about architectural compatibility with the edge. The Root Cause: The "Sidecar" Tax To understand why Prisma struggles in serverless environments, we must look at its architecture. Prisma is not a standard TypeScript library. When you import  PrismaClient , you are effectively importing a bridge to a binary engine written in Rust. The Query Engine:  Prisma relies on a heavy Rust b...
