南大通用GBase 8a在V95版本不同列、不同行数文件加载性能测试对比

发表于2021年2月4日2021年5月8日作者 laozizhu

本文针对10-1000列的表，10-1000万行数据(int),进行加载性能测试，验证加载性能，提供用户项目参考。

相同列数，不同数据库版本，开启事务影响等，请参考 8a针对宽表1000列的小文件加载不同版本配置性能测试

测试结果汇总

在笔记本虚拟机单节点4核4G内存的GBase 8a V952开始事务的环境下，常规的20-50列的表，10万行以内，也能在5秒以内完成；低于1万行的数据，即使1000列，也能在10秒内完成。

行数	10列	20列	50列	100列	200列	500列	1000列
10	0.28	0.39	0.32	0.31	0.41	0.58	0.67
100	0.42	0.33	0.37	0.32	0.46	0.67	0.89
1000	0.31	0.28	0.45	0.56	0.68	0.97	1.69
10000	0.39	0.51	0.75	1.07	1.57	3.92	8.63
100000	0.95	1.11	2.26	4.30	8.36	28.30	64.61
1000000	2.91	5.08	11.96	25.14
10000000	23.53

环境

笔记本虚拟机，4核4G内存。
