The setup:
- 2-node Cassandra 2.0.7.31 cluster
- replicas=1
- DataStax java driver 2.0
Problem
I am using Datastax java driver for load balancing.
I and generating 50000+ thread load by Jmeter
but getting very low TPS. near about 1700 tps
I have not changed any performance related parameter In cassandra.yaml
can any one suggest which parameter should I use to get satisfactory TPS. I herd Most of the Folks are getting 10000+ tps with Cassandra.
Thanks in advance
By TPS you mean Ligthweight Transaction Per Second or just Operation per second .
If it is Operation Per Second .
Figure out whats your Network bandwidth Speed of your Disk Number of cores on your machine
run queries and at run time figure out what is the bottleneck , commmands to figure out bottleneck are * network: dstat 2
- cpu + disk: iostat -c -xc 3
- cpu cores: mpstat -P ALL 1
- memeory : free -m
gc : jstat -gc pid 2
do remember either of this bottleneck can be their at server or your client side .
