Batch-optimized render and fetch architecture

Implementations include a batch-optimized render and fetch architecture. An example method performed by the architecture includes receiving a request from a batch process to render a web page and initializing a virtual clock and a task list for rendering the web page. The virtual clock stands still when a request for an embedded item is outstanding and when a task is ready to run. The method may also include generating a rendering result for the web page when the virtual clock matches a run time for a stop task in the task list, and providing the rendering result to the batch process. Another example method includes receiving a request from a batch process to render a web page, identifying an embedded item in the web page, and determining, based on a rewrite rule, that the embedded item has content that is duplicative of content for a previously fetched embedded item. 实现方式包括批处理优化的渲染和获取架构。由该架构执行的示例方法包括：从批处理进程接收渲染网页的请求并且将虚拟时钟和任务列表初始化以用于渲染网页。当对嵌入式项的请求未完成时并且当任务准备好运行时，虚拟时钟保持静止。该方法还可包括：当虚拟时钟与任务列表中的停止任务的运行时间匹配时生成网页的
