本文探讨了如何通过Nginx Lua API进行网络及磁盘I/O操作以避免阻塞Nginx事件循环，强调使用标准Lua I/O库进行小规模磁盘操作，并推荐通过Nginx子请求代理所有网络及磁盘I/O操作来获得最佳性能。

Network I/O operations in user code should only be done through the Nginx Lua API calls as the Nginx event loop may be blocked and performance drop off dramatically otherwise. Disk operations with relatively small amount of data can be done using the standard Lua io library but huge file reading and writing should be avoided wherever possible as they may block the Nginx process significantly. Delegating all network and disk I/O operations to Nginx's subrequests (via the ngx.location.capture method and similar) is strongly recommended for maximum performance.
