Xiuno BBS 是一款国产、小巧、稳定、支持在大数据量下仍然保持高负载能力的轻型论坛。它只有 21 个表，源代码压缩后 600k 左右，运行速度非常快，处理单次请求在 0.01 秒级别，在有 APC、XCache 的环境下可以跑到 0.00x 秒，对第三方类库依赖极少，仅仅前端依赖 jquery.js/zepto.js，作者认为它就像一辆纯手工打造的法拉利，动力强劲，没有一丝赘肉，方便部署和维护，是一个非常好的二次开发的基石。

Xiuno BBS 4.0 采用 Bootstrap 4 + JQuery 3 作为前端类库，全面支持移动端浏览器；后端 XiunoPHP 4.0 支持了 NoSQL 的方式操作各种数据库，这个版本是一个巨大的飞跃。(Xiuno BBS is a domestic, compact, stable, support for a large amount of data still maintain a high load capacity of the light forum. It has only 21 tables, source code compressed 600k, run very fast, processing a single request in 0.01 second level, in APC, XCache environment can run for 0.00x seconds, little reliance on third party libraries, the front only rely on jquery.js/zepto.js, the author thinks that it is like a pure hand-made Ferrari, strong power, no fat, easy deployment and maintenance, is a very good two development foundation.
Xiuno BBS 4 uses Bootstrap 4 + JQuery 3 as the front end class library, fully supports mobile browser. The backend XiunoPHP 4 supports NoSQL's way to operate various databases, which is a great leap.)
