    点击是每次请求就+1
    其它两个都太简单了

    @pimin xxx 次点击存到数据库？每次点击在往数据库中写一次？这样会不会影响性能？

    @triThirty 用内存来做的话影响应该不大吧。一段时间同步一次到硬盘就好

    @triThirty 一般数据库也有缓存的吧。小操作一定量后才会写入磁盘

    v2ex 也不是静态网站,每打开一个页面,要查询标题,内容,标签,评论,发布时间,修改时间
    诸如此类这么多字段,也不在意加一个点击次数是不是.

    一般都是在读取文章数据的同时顺带+1 。
    只要不是 MySQL 这种操作会锁表的数据库，一般来说这个操作几乎没啥影响。
