MemSQL、SQLFire、Oracle XE性能对比测试

来源：互联网发布：sql语句里日期取变量编辑：程序博客网时间：2024/06/01 07:38

1.软件版本

MemSQL 3.1

Pivotal SQLFire 1.1.2

Oracle 11g XE

2.测试环境

宿主机

OS：Windows 7 64位专业版

CPU：i7-3770 3.4GHz

内存：16G

硬盘：大于800G

VMware虚拟机

OS：CentOS 6.3 64位

内存：16G

其中MemSQL运行于虚拟机，SQLFire和Oracle直接运行于宿主机

SQLFire只开启一个server member

3.DDL

MemSQL

DROP TABLE t_main;DROP TABLE t_rel1;DROP TABLE t_rel2;DROP TABLE t_rel3;create table t_main(rec_id BIGINT not null  PRIMARY KEY,c1 DOUBLE PRECISION,c2 BIGINT,c3 VARCHAR(100),c4 VARCHAR(100),c5 VARCHAR(100),c6 VARCHAR(100)) ;create table t_rel1(rec_id BIGINT not null  PRIMARY KEY,main_id BIGINT,c1 DOUBLE PRECISION,c2 BIGINT,c3 VARCHAR(100),c4 VARCHAR(100),c5 VARCHAR(100),c6 VARCHAR(100)) ;create table t_rel2(rec_id BIGINT not null  PRIMARY KEY,main_id BIGINT,c1 DOUBLE PRECISION,c2 BIGINT,c3 VARCHAR(100),c4 VARCHAR(100),c5 VARCHAR(100),c6 VARCHAR(100)) ;create table t_rel3(rec_id BIGINT not null  PRIMARY KEY,main_id BIGINT,c1 DOUBLE PRECISION,c2 BIGINT,c3 VARCHAR(100),c4 VARCHAR(100),c5 VARCHAR(100),c6 VARCHAR(100)) ;create index rel1main on t_rel1(main_id);create index rel2main on t_rel2(main_id);create index rel3main on t_rel3(main_id);

SQLFire

DROP TABLE t_main;DROP TABLE t_rel1;DROP TABLE t_rel2;DROP TABLE t_rel3;create table t_main(rec_id BIGINT not null  PRIMARY KEY,c1 DOUBLE PRECISION,c2 BIGINT,c3 VARCHAR(100),c4 VARCHAR(100),c5 VARCHAR(100),c6 VARCHAR(100)) PERSISTENT;create table t_rel1(rec_id BIGINT not null  PRIMARY KEY,main_id BIGINT,c1 DOUBLE PRECISION,c2 BIGINT,c3 VARCHAR(100),c4 VARCHAR(100),c5 VARCHAR(100),c6 VARCHAR(100)) PERSISTENT;create table t_rel2(rec_id BIGINT not null  PRIMARY KEY,main_id BIGINT,c1 DOUBLE PRECISION,c2 BIGINT,c3 VARCHAR(100),c4 VARCHAR(100),c5 VARCHAR(100),c6 VARCHAR(100)) PERSISTENT;create table t_rel3(rec_id BIGINT not null  PRIMARY KEY,main_id BIGINT,c1 DOUBLE PRECISION,c2 BIGINT,c3 VARCHAR(100),c4 VARCHAR(100),c5 VARCHAR(100),c6 VARCHAR(100)) PERSISTENT;create index rel1main on t_rel1(main_id);create index rel2main on t_rel2(main_id);create index rel3main on t_rel3(main_id);

Oracle

DROP TABLE t_main;DROP TABLE t_rel1;DROP TABLE t_rel2;DROP TABLE t_rel3;create table t_main(rec_id NUMBER(19,0) not null  PRIMARY KEY,c1 DOUBLE PRECISION,c2 NUMBER(19,0),c3 VARCHAR2(100),c4 VARCHAR2(100),c5 VARCHAR2(100),c6 VARCHAR2(100)) ;create table t_rel1(rec_id NUMBER(19,0) not null  PRIMARY KEY,main_id NUMBER(19,0),c1 DOUBLE PRECISION,c2 NUMBER(19,0),c3 VARCHAR2(100),c4 VARCHAR2(100),c5 VARCHAR2(100),c6 VARCHAR2(100)) ;create table t_rel2(rec_id NUMBER(19,0) not null  PRIMARY KEY,main_id NUMBER(19,0),c1 DOUBLE PRECISION,c2 NUMBER(19,0),c3 VARCHAR2(100),c4 VARCHAR2(100),c5 VARCHAR2(100),c6 VARCHAR2(100)) ;create table t_rel3(rec_id NUMBER(19,0) not null  PRIMARY KEY,main_id NUMBER(19,0),c1 DOUBLE PRECISION,c2 NUMBER(19,0),c3 VARCHAR2(100),c4 VARCHAR2(100),c5 VARCHAR2(100),c6 VARCHAR2(100)) ;create index rel1main on t_rel1(main_id);create index rel2main on t_rel2(main_id);create index rel3main on t_rel3(main_id);

4.测试数据

4张表，每张100万条数据

生成数据的代码片段为

String sql = "insert into t_main(rec_id,c1,c2,c3,c4,c5,c6) values(?,?,?,?,?,?,?)";PreparedStatement st1 = conn.prepareStatement(sql);sql = "insert into t_rel1(rec_id,main_id,c1,c2,c3,c4,c5,c6) values(?,?,?,?,?,?,?,?)";PreparedStatement st2 = conn.prepareStatement(sql);sql = "insert into t_rel2(rec_id,main_id,c1,c2,c3,c4,c5,c6) values(?,?,?,?,?,?,?,?)";PreparedStatement st3 = conn.prepareStatement(sql);sql = "insert into t_rel3(rec_id,main_id,c1,c2,c3,c4,c5,c6) values(?,?,?,?,?,?,?,?)";PreparedStatement st4 = conn.prepareStatement(sql);long a = System.currentTimeMillis();for (int i = 1; i <= count; i++) {st1.setLong(1, i);st1.setDouble(2, i * 0.1);st1.setLong(3, i * 2);st1.setString(4, "c3_" + i);st1.setString(5, "c4_" + i);st1.setString(6, "c5_" + i);st1.setString(7, "c6_" + i);st1.executeUpdate();st2.setLong(1, i);st2.setLong(2, i);st2.setDouble(3, i * 0.2);st2.setLong(4, i * 3);st2.setString(5, "c3_" + i);st2.setString(6, "c4_" + i);st2.setString(7, "c5_" + i);st2.setString(8, "c6_" + i);st2.executeUpdate();st3.setLong(1, i);st3.setLong(2, i);st3.setDouble(3, i * 0.3);st3.setLong(4, i * 4);st3.setString(5, "c3_" + i);st3.setString(6, "c4_" + i);st3.setString(7, "c5_" + i);st3.setString(8, "c6_" + i);st3.executeUpdate();st4.setLong(1, i);st4.setLong(2, i);st4.setDouble(3, i * 0.4);st4.setLong(4, i * 5);st4.setString(5, "c3_" + i);st4.setString(6, "c4_" + i);st4.setString(7, "c5_" + i);st4.setString(8, "c6_" + i);st4.executeUpdate();}

5.测试结果

4张表，每张插入100万数据，消耗时间对比

单位：毫秒

MemSQLSQLFireOracle6247651961401289811

以下为查询测试，均执行10次求得平均消耗时间（不包含首次执行）

单位：毫秒

查询测试一：单表整型字段比较

select count(*) from t_main where c2>1000;

MemSQLSQLFireOracle2167558

查询测试二：单表like

select count(*) from t_main where c4 like '%c%';

MemSQLSQLFireOracle41875133

查询测试三：多表关联浮点数sum

select sum(m.c1+r1.c1+r2.c1+r3.c1) "rt" from t_main m,t_rel1 r1,t_rel2 r2,t_rel3 r3 where m.rec_id=r1.main_id and m.rec_id=r2.main_id and m.rec_id=r3.main_id;

MemSQLSQLFireOracle1365146402077

查询测试四：多表关联整型sum

select sum(m.c2+r1.c2+r2.c2+r3.c2) "rt" from t_main m,t_rel1 r1,t_rel2 r2,t_rel3 r3 where m.rec_id=r1.main_id and m.rec_id=r2.main_id and m.rec_id=r3.main_id;

MemSQLSQLFireOracle1360102572084

6.总结

测试过程中CPU、内存使用均未超过50%

插入性能SQLFire最高，MemSQL其次，Oracle最慢，MemSQL效率约是Oracle的两倍

查询性能MemSQL最高，Oracle其次，SQLFire最慢（慢的出奇。。。），MemSQL效率约是Oracle的两倍

不知道怎样的环境能测出30倍性能的提升。。。
