mysql linux内核_mysql 5.7.15 vs mysql 5.6.31性能测试以及不同linux内核性能比较
最近,将部分开发和测试环境的mysql升级到5.7之后,今天抽时间测试了下5.6和5.7 PK查询的性能,使用mysqlslap进行测试,测试结果发现在低配下,percona 5.6.31大约比5.7.15快20-30%左右,percona 5.7.15比mysql企业版5.7.16快10%左右,如下:

因为mysql 5.7相比mysql 5.6增加了很多新的特性、同时新增了很多后台线程,所以在达到mysql 5.6的最大并发之前,mysql 5.6在性能上比mysql 5.7更高并不奇怪。因为我们大量服务器部署于阿里云和虚拟化环境,所以不打算也不计划测试在64GB以上的环境。后续会测试在16C/16GB和16C/32GB环境下两者的情况。
上述测试基于centos 7.2,linux内核3.10。
同时,需要注意的是,在不同的vm实例中,即使配置和型号完全相同,也有可能出现TPS上下相差10-20%的情况,这一点尤其需要注意,因为任何时候cpu/内存/服务器进程/线程等都可能在不同程度的运行,即使是空环境亦如此。另外,还需要注意不同的linux/内核版本可能导致性能相差比较大。
在另一个centos 6.3,内核2.6.32的VM实例中,percona 5.6.31的测试如下(平均TPS达到22000)(7.0相同配置下平均18000左右):
[root@dev-server1 ~]# mysqlslap -h172.18.30.193 -P3306 --concurrency=200 --create-schema='spider' --query='select * from test_250byte where id=1;' --number-of-queries=1000000 -uroot -pLd123123

基本上可以看出,在8C的配置下,mysql 5.6和5.7的性能已经比较接近的,按说配置再增加的情况下,5.7的扩展性会比5.6更好,且新增的很多额外线程的消耗会被抵销。
