  • GreatSQL社区原创内容未经授权不得随意使用，转载请联系小编并注明来源。
  • GreatSQL是MySQL的国产分支版本，使用上与MySQL一致。

  1. 无论ibp（innodb_buffer_pool_size）是否充足，MySQL的性能都远不如GreatSQL。

  2. MySQL的性能平均约为GreatSQL的70%（最高84.5%，最低61.7%）。

  3. 在ibp充分的情况下，随着并发数的增加，MySQL并没有表现出该有的性能提升，反倒掉头向下，可见还是不够稳定。

  4. 在ibp不够的情况下，GreatSQL开启thread pool性能有所提升；当ibp充足的情况下，区别就不大了。

3.1 测试工具

sysbench

/usr/local/bin/sysbench --version
sysbench 1.1.0

P.S，该版本是楼方鑫修改后的，增加了99.9%的RT统计值，例如：

3.2 测试模式

  • 利用sysbench生成64个表，每个表1250万条记录。
  • 数据库总大小约191G。
  • sysbench采用 oltp_read_write 模式。
  • innodb_flush_method = O_DIRECT_NO_FSYNC。
  • GreatSQL在需要时才开启thread pool，MySQL不支持thread pool。
  • 默认关闭InnoDB PQ。
  • 因为没有额外测试机，所以采用本地socket方式连接，顺便关闭网络监听设置。
  • 测试资源有限，所以只测试单机模式，没有开启MGR。

3.3 测试机硬件配置

  • 最大物理内存：376G，但数据库分配IBP时分别为48G、96G、144G、192G，没有将物理内存全部耗尽。

  • 磁盘：Dell NVMe SSD

    $ nvme list | grep nvme1
    /dev/nvme1n1 90L0A019TAHR
    Dell Express Flash CD5 3.84T SFF 1
    2.86 TB / 3.84 TB 512 B + 0 B 1.1.1

  • 文件系统、ioscheduler

    $ df -hT | grep nvme1
    /dev/nvme1n1p1 xfs 3.5T 2.9T 706G 81% /data_nvme1n1p1

    $ cat /sys/block/nvme1n1/queue/scheduler
