　　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;
 
　　插入数据

　　说明：每次都是空表插入数据

　　插入10000 Record

Heap engine insert 10000 record used time: 3.5008587837219MyISAM engine insert 10000 record used time:

4.5881390571594
 
50000 Record

Heap engine insert 50000 record used time: 19.895354986191MyISAM engine insert 50000 record used time: 33.866044998169
 
100000 Record

Heap engine insert 100000 record used time: 36.200875997543MyISAM engine insert 100000 record used time: 68.34194111824
 
200000 Record

Heap engine insert 200000 record used time: 68.00207901001MyISAM engine insert 200000 record used time: 125.26263713837
 
　　查询数据

　　表里分表有：200000条记录，两个表数据一致

　　直接select，10000次，每次取100条记录

Heap engine select 10000 times, 100 record used time: 12.122506141663MyISAM engine select 10000 times, 100 record used time: 19.512896060944
 
　　直接select，1000次，每次取10000条记录

Heap engine select 1000 times, 10000 record used time: 111.54126811028MyISAM engine select 1000 record used time: 116.79438710213
 
　　增加where条件，1000次，每次取10000条记录

Heap engine select 1000 times, 10000 record used time: 111.52102303505MyISAM engine select 1000 times, 10000 record used time: 117.68481087685
