问题
I installed the Cassandra 2.0.0 on RedHat Linux using YUM. It's single node with the default setting. the Linux has 4 cores and 8G RAM. When I ran the following write/read single column family testing. the produced result seems pretty slow. Please advice how to make it fast. thanks.
Each row has 100 columns.
Cassandra Write
Row Byte Time (ms) 2 110K 17 30 162K 170 100 540K 562 500 2700K 2459 1000 5408K 5570 2000 10797K 8707 4000 21583K 3975 9000 17799K 10600
Cassandra Read**
It took 6.5 second to read 9000 rows from a single column family.
