MySQL 5.7 vs 8.0,性能PK mysql教程栏目介绍MySQL 5.7和MySQL 8.0的性能对比。

背景

测试mysql5.7和mysql8.0 分别在读写、只读、只写模式下不同并发时的性能(tps,qps)

前提
  • 测试使用版本为mysql5.7.22和mysql8.0.15
  • sysbench测试前先重启mysql服务,并清空os的cache(避免多次测试时命中缓存)
  • 每次进行测试都是新生成测试数据后再进行mysql5.7和mysql8.0的测试
  • 每次测试时保证mysql5.7和mysql8.0的配置参数一致
环境

机器

测试
  • 在不同的持久化策略下(binlog, redo log持久化)mysql5.7和mysql8.0 在读写模式、只读模式、只写模式(oltp_read_write,oltp_read_only,oltp_write_only)下的性能表现

  • sysbench 测试时间为60s,测试的表数量为20

  • 测试分别在双1模式(安全性)和0 2模式(高性能)下进行

  • SHOW GLOBAL VARIABLES WHERE Variable_name IN('sync_binlog','innodb_flush_log_at_trx_commit'); +--------------------------------+-------+ | Variable_name | Value | +--------------------------------+-------+ | innodb_flush_log_at_trx_commit | 1 | | sync_binlog | 1 | +--------------------------------+-------+

mysql5.7和mysql8.0 在读写模式下的表现

  • 双1 配置,读写模式下,mysql5.7.22 和mysql8.0.15 tps 、qps 性能差不多,mysql8.0.15 在120 线程并发时,性能出现了下降抖动:

mysql5.7和mysql8.0 在只读模式下的表现

  • 双1 配置,只读模式下,mysql5.7.22 的tps、qps比mysql8.0.15 好1/3 左右;并发线程数增加后,tps、qps并没有随着增加,反而出现了下降的趋势。

mysql5.7和mysql8.0 在只写模式下的表现

  • 双1 配置,只写模式下,随着并发数的上升,mysql5.7.22 的性能比mysql8.0.15 好1/4左右。

0 2 模式下

SHOW GLOBAL  VARIABLES WHERE Variable_name IN('sync_binlog','innodb_flush_log_at_trx_commit');
+--------------------------------+-------+
| Variable_name                  | Value |
+--------------------------------+-------+
| innodb_flush_log_at_trx_commit | 2     |
| sync_binlog                    | 0   |
+--------------------------------+-------+复制代码

mysql5.7和mysql8.0 在读写模式下的表现

  • 0 2配置,读写模式下,并发数低时,mysql5.7.22性能好于mysql8.0.15; 并发数比较高时,mysql8.0.15 性能好于mysql5.7.22;在80 线程的并发以上时,性能开始下降。

mysql5.7和mysql8.0 在只读模式下的表现

  • 0 2配置,只读模式下,mysql5.7.22性能比mysql8.0.15 好1/3左右;随着并发数的上升,性能也没有上升,反而有下降的趋势.

mysql5.7和mysql8.0 在只写模式下的表现

  • 0 2 配置,只写模式下,mysql5.7.22的tps 抖动比较大;mysql5.7.22 的qps比mysql8.0.15好1/3左右
结论
  • 整体来看,mysql5.7.22在读写模式、只读模式、只写模式下的表现是优于mysql8.0.15的
  • 随着并行数的增加,性能表现不会也跟着增加,还会出现下降
  • 本次测试结果是在配置很低的情况下进行的,不代表绝对
