+`@utoo/web` is a powerful library that enables you to run a complete web development environment, including a virtual file system, dependency management, and a build process, entirely within the browser. It deeply integrates [`utoopack`](https://github.com/utooland/utoo), a new builder based on [`Rust`](https://www.rust-lang.org/) and [`turbopack`](https://nextjs.org/docs/app/api-reference/turbopack), and leverages modern web technologies like Web Workers, Service Workers, and the Origin Private File System (OPFS) to provide a seamless and fast development experience without a backend server.
 
 ## Core Concepts
 
 Before diving into the API, it's important to understand the four main components that make `@utoo/web` work:
 
 1.  **Virtual File System**: The entire project, including source code and `node_modules`, lives in the browser's Origin Private File System (OPFS). The `Project` class provides a Node.js-like `fs` interface to interact with it.
 2.  **Project Main Worker**: The core logic of the `Project` instance runs within its own Web Worker. The `Project` object you interact with in the main thread is a proxy that delegates all core tasks (like file system operations) to this worker. This architecture is key to keeping the UI responsive.
-3.  **Thread Worker**: Heavy tasks like bundling and compilation are offloaded to a dedicated Web Worker. This ensures the main UI thread remains responsive, even during a build.
+3.  **Thread Worker**: Heavy tasks like bundling and compilation are offloaded to a dedicated Web Worker. This ensures the main UI thread remains responsive, even during a build. We have ported [`tokio`](https://github.com/utooland/tokio) to the browser to take full advantage of multi-core CPUs for improved performance. The **Thread Worker** will be completely taken over by the tokio runtime.
 4.  **Service Worker**: A Service Worker acts as a local server. It intercepts requests from the preview `iframe`, reads the corresponding files from the OPFS, and serves them back, allowing you to preview your built application.

+## Notes
+* Due to the current default memory allocator for Rust, [`dlmalloc`](https://github.com/alexcrichton/dlmalloc-rs), having less than ideal performance on multi-threaded `wasm`, we are currently trying to support [`mimalloc`](https://github.com/microsoft/mimalloc) with reference to [`emscripten`](https://emscripten.org/docs/tools_reference/settings_reference.html#malloc)'s solution. Once successful, the build speed will be greatly improved;

+* Advanced features of turbopack such as [`webpack loaders`](https://nextjs.org/docs/app/api-reference/config/next-config-js/turbopack#configuring-webpack-loaders), [`persistent caching`](https://nextjs.org/docs/app/api-reference/config/next-config-js/turbopackPersistentCaching), are also in the plan and will be supported directly in the browser in the future.

 ## 核心概念
 
 在深入了解 API 之前，理解构成 `@utoo/web` 的四个主要组件非常重要：
 
-1.  **虚拟文件系统 (Virtual File System)**：整个项目，包括源代码和 `node_modules`，都存在于浏览器的源私有文件系统（OPFS）中。`Project` 类提供了一个类似 Node.js `fs` 的接口来与其交互。

 2.  **Project Main Worker**：`Project` 实例的核心逻辑运行在它自己的 Web Worker 中。您在主线程中与之交互的 `Project` 对象实际上是一个代理，它将所有核心任务（如文件系统操作）委托给此 Worker。这种架构是保持 UI 响应流畅的关键。
-3.  **Thread Worker**：像打包和编译这样的重度任务被卸载到一个专用的 Web Worker 中。这确保了即使在构建过程中，主 UI 线程也能保持响应。

 4.  **Service Worker**：Service Worker 充当本地服务器。它拦截来自预览 `iframe` 的请求，从 OPFS 中读取相应的文件，并将其提供回去，从而允许您预览构建好的应用程序。
