GreatSQL vs MySQL性能测试来了，你学会了吗？
发布时间：2025-11-03 03:02:52 来源：创站工坊 作者：人工智能
1.结论先行
无论ibp（innodb_buffer_pool_size）是试学否充足，MySQL的试学性能都远不如GreatSQL。MySQL的试学性能平均约为GreatSQL的70%（最高84.5%，最低61.7%）。试学在ibp充分的试学情况下，随着并发数的试学增加，MySQL并没有表现出该有的试学性能提升，反倒掉头向下，试学可见还是试学不够稳定。在ibp不够的试学情况下，b2b供应网GreatSQL开启thread pool性能有所提升；当ibp充足的试学情况下，区别就不大了。试学MySQL vs GreatSQL性能数据对比
