服务器配置：
处理器：Xeon E3-1230 V2
内存：16G DDR3 1600Mhz
硬盘：1TB 企业级硬盘
我现在的配置
[mysqld]

[mysqldump]
quick
max_allowed_packet = 16M
[mysql]

[myisamchk]
key_buffer_size = 256M
sort_buffer_size = 4M
read_buffer = 2M
write_buffer = 2M
[mysqlhotcopy]
interactive-timeout
请问如何优化一下呢，数据库读写量大。

读写频繁，应该怎么提高效率呢？

你这个，其实没啥可做的……条件都不具备
首先，硬盘性能不行，得用高速 sas 或者 ssd 盘 其次，数据应该转 innodb 而不是用 myisam 第三，加内存解决一切问题。你这就 16G 就没啥可说的了，捉襟见肘，没啥可调的 |
