我已经有这个问题超过1周了。我已经完成了其他人在stackoverflow上遇到的类似问题。我正在运行Mysql 5.6.10。
随机发生。但每5分钟左右，提交需要很长时间。转换插入物的大小通常约为1-2000行。
我一直在改变设置，有点迷失了我决定在这里提出问题。
我的插入/更新是由我的程序生成的sqlfiles。然后我有一个Windows服务，每1.5分钟运行一次处理文件。我在事务模式下构建了许多sql文件的字符串。它在5次中有4次非常流畅，但是5次中有1次是卡纸。
它通常发生在同一个表中，并且大部分时间都是关于插入的，但也会在更新时发生。所以我怀疑它与我的表格的结构有关，但在你解决之前你永远不会知道：）
这是表结构
CREATE TABLE `int_links_root_1` (
`IntLinksRootId` bigint(20) NOT NULL AUTO_INCREMENT,
`UrlId` int(11) NOT NULL,
`Link` varchar(2000) NOT NULL,

`Title` varchar(2000) DEFAULT NULL,
`PageText` varchar(8000) DEFAULT NULL,
`Added` datetime DEFAULT NULL,

我尝试了所有不同的innodb_flush_log_at_trx_commit设置。我确信我的查询是最佳的，因为它们运行得非常快，我几乎可以肯定它与我的刷新有关。我也试过禁用自动提交，但它仍然发生。查询缓存已禁用。但任何想法都非常受欢迎。也许我的磁盘只是放慢速度？
系统尚未投入生产，因此我可以重新启动它并测试任何建议。
如果我能提供更多细节，请告诉我。

您确定之前的提交已经完成了吗？我不熟悉mysql的内部结构，但不能重建索引，这对于大型表来说真的很慢。或者你可以一次运行多个查询，但第五个查询只是在rhreads计数之外并且在队列中等待休息完成。
