一，測試服務器配置：
Cpu: 2*4核Intel(R) Xeon(R) E5405 @ 2.00GHz
內存：4G
存儲：36塊1T的7.2K的SATA組成raid0。使用其中的1T
Mysql版本：5.1.45-community-log MySQL Community Server (GPL)
二，建測試表：
Myisam不分區不分表，單表10億數據量：
create table biguser
(
ID bigint not null auto_increment comment ‘自增ID’,
Username varchar(30) not null comment ‘用戶名’,
sex tinyint not null comment ‘性別’,
birthday datetime not null comment ‘生日’,
email varchar(50) not null comment ‘郵箱’,
tel int not null comment ‘手機’,
intro varchar(255) not null comment ‘個人簡介’,
primary key (ID)
)
type = MYISAM
default charset=utf8;
Myisam不分區，分10個表，單表1億數據量：
create table user01
(
ID bigint not null auto_increment comment ‘自增ID’,
Username varchar(30) not null comment ‘用戶名’,
sex tinyint not null comment ‘性別’,
birthday datetime not null comment ‘生日’,
email varchar(50) not null comment ‘郵箱’,
tel int not null comment ‘手機’,
intro varchar(255) not null comment ‘個人簡介’,
primary key (ID)
)
type = MYISAM
default charset=utf8;
*一共10個表,user01,user02,…,user10
Myisam用id進行hash分區，分10個區，每個分區1億數據：
create table puser
(
ID bigint not null auto_increment comment ‘自增ID’,
Username varchar(30) not null comment ‘用戶名’,
sex tinyint not null comment ‘性別’,
birthday datetime not null comment ‘生日’,
email varchar(50) not null comment ‘郵箱’,
tel int not null comment ‘手機’,
intro varchar(255) not null comment ‘個人簡介’,
primary key (ID)
)
type = MYISAM
default charset=utf8
partition by hash(ID)
partitions 10;
Innodb用id進行hash分區，分10個區，每個分區1億數據：
create table iuser
(
ID bigint not null auto_increment comment ‘自增ID’,
Username varchar(30) not null comment ‘用戶名’,
sex tinyint not null comment ‘性別’,
birthday datetime not null comment ‘生日’,
email varchar(50) not null comment ‘郵箱’,
tel int not null comment ‘手機’,
intro varchar(255) not null comment ‘個人簡介’,
primary key (ID)
)
type = Innodb
default charset=utf8
partition by hash(ID)
partitions 10;
Innodb不分區不分表，單表10億數據量：
create table ibiguser
(
ID bigint not null auto_increment comment ‘自增ID’,
Username varchar(30) not null comment ‘用戶名’,
sex tinyint not null comment ‘性別’,
birthday datetime not null comment ‘生日’,
email varchar(50) not null comment ‘郵箱’,
tel int not null comment ‘手機’,
intro varchar(255) not null comment ‘個人簡介’,
primary key (ID)
)
type = Innodb
default charset=utf8;
三，數據生成
利用power design生成100萬不重復的數據的基礎表，然后將此表數據用mysqlslap工具重復插入到目標表，可以快速生成海量數量表。最終數據文件大小都在170G左右(分表情況單表17G數據文件)
插入100萬記錄到目標表的性能如下
單位（秒）：
| Myisam不分區 | Myisam分區 | Innodb不分區 | Innodb分區 |
| 10.514 | 9.114 | 16.258 | 16.893 |
可見非並發的大量數據插入myisam分區性能最佳，myisam不分區次之，innodb分區較差。
四，壓力測試
利用mysql5.1自帶的壓力測試工具mysqlslap對以上四種情況進行了壓力測試，測試結果如下(單位：秒)：
| myisam 未分區 |
myisam 分區 |
Myisam 分表 |
Innodb 未分區 |
innodb 分區 |

*運行了一個100條語句的批查詢，看非並發情況下的查詢效率，查詢語句見附一。
*利用存儲過程進行一個hash處理，去對不同的表進行數據操作，見附二。
五，結論：
一，在高並發情況下，innodb的分區表的增，刪，改，查的性能都優於myisam引擘，特別是在高並發刪除和更新的場合下，兩者相差可以達到20-30倍。
二，myisam的分區表(10個分區)和未分區表的性能相差不大，略優於未分區表。
三，myisam分區表(10個分區)的插入性能與分表(10個表)差不多，但查詢性能要好30%左右。但刪除與更新的性能分表要遠遠好於分區。
四，innodb分區表和未分區表查詢和插入在低並發下，相差40%。但在並發性不斷增加的情況下，性能相差不大。刪除和更新性能則一直相近。
