插入的文章见：

1,机器为4核16G内存，脚本和数据库在同一机器上跑，插入的速度还能快更多。
2,mysql为5.1.30


回复要先做题，太麻烦了，直接改原贴。
对1楼的回复，需要说明几个问题
1，oracle版本和基本配置(oracle所用的内存，缓冲是多大？)
2，所在的硬件环境

---------------
3，我的相关文章注明了，插入脚本和数据库是在同一个机器上，为了模拟真实的负载，100个并发连接全是单独直接连接数据库，并没有把全部硬件资源用在数据库上，mysqld的配置也有限
4，即使oracle在大数据量快一点也是正常的，但是这足够证明mysql不慢！！！单表这个插入速度的量对绝大部分应用足够了。

mysql插入响应速度是很快的，但是并发查询似乎不是很快。如果有这么多条的话，还是建议用oracle或者mysql集群，否则硬盘的速度跟不上的。

1 楼 seujacky 2009-07-29  

看见在插入数据量近6000W的时候，还能达到1200条/秒左右



这个也叫快？前天我插入的速度是1万条每秒。数据库是oracle的。java程序。数据还是从文件中解析出来的文件有300多个数据量是6千多万条。
