MyISAM引擎和Heap引擎执行速度的性能测试
2008-10-17 11:12:25 来源:WEB开发网MyISAM引擎和Heap引擎执行速度的性能测试:
测试环境:
CPU: Intel Pentium4 2.66GHz
Memory: 1GB
Disk: 73GB/SCSI
OS: FreeBSD 4.11
PHP: PHP 5.2.1
MySQL: MySQL 4.1.23b
前期工作:
my.cnf:
max_heap_table_size = 128M
建表:
use test;
--
-- Store engine heap
--
CREATE TABLE `tbl_heap` (
`id` int(11) NOT NULL auto_increment,
`name` varchar(32) NOT NULL default ´´,
`email` varchar(32) NOT NULL default ´´,
`summary` varchar(255) default ´´,
KEY `id` (`id`)
) ENGINE=HEAP DEFAULT CHARSET=gbk;
--
-- Store engine myisam
--
CREATE TABLE `tbl_isam` (
`id` int(11) NOT NULL auto_increment,
`name` varchar(32) NOT NULL default ´´,
`email` varchar(32) NOT NULL default ´´,
`summary` varchar(255) default ´´,
KEY `id` (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=gbk;
