和机器性能,还有建表方式都有关系。 |

我在8核8G的机器上测试性能,为何只能达到官方的3分之1,或者4分之1呢?
下面是一个client,一次一条数据。只有5k,官方15k的吞吐量
[root@ tdengine]# ./tdengineTest -dataDir /root/robin/taosdb/testdata/ -numOfFiles 1 -clients 1 -rowsPerRequest 1 -w 1
write data
---- clients: 1
---- dataDir: /root/robin/taosdb/testdata/
---- numOfFiles: 1
---- rowsPerRequest: 1
Thread 1, writing sID 0, eID 0
open file /root/robin/taosdb/testdata//testdata0.csv success
---- Spent 189.524994 seconds to insert 1000000 records, speed: 5276.349121 Rows/Second
下面是一个client,一次100条数据。只有19k,官方65k的吞吐量
[root@tdengine]# ./tdengineTest -dataDir /root/robin/taosdb/testdata/ -numOfFiles 1 -clients 1 -rowsPerRequest 100 -w 1
write data
---- clients: 1
---- dataDir: /root/robin/taosdb/testdata/
---- numOfFiles: 1
---- rowsPerRequest: 100
Thread 1, writing sID 0, eID 0
open file /root/robin/taosdb/testdata//testdata0.csv success
---- Spent 5.198000 seconds to insert 1000000 records, speed: 192381.687500 Rows/Second
