+Elysia speed is not only achieved by optimization for specific runtime eg. Bun native features like `Bun.serve.routes`, but also by the way Elysia handles route registration and request handling.
 
 Elysia has an **JIT "compiler"** embedded within its core since [Elysia 0.4](/blog/elysia-04) (30 Mar 2023) at (*src/compose.ts*) using `new Function(...)` or also known as `eval(...)`.

 ### Initial Request Overhead
 The first time a request is made to a specific route, Elysia needs to analyze the route handler code and generate the optimized code.
 
-This process is relatively **very fast** and usually takes < 0.005ms per route in most cases on a modern CPU and happend only **once per route**. But it is still an overhead.

 Despite the maintainability challenges, the trade-offs made by Elysia's JIT "compiler" are worth it for the significant performance gains it provides and aligns with our goal to provide a fast foundation for building high-performance server.
