I'm trying to measure the performance of Geode I have 3 identical hosts to test it. I created a partitioned region.
I started a geode cluster with one server. I do "get" and "put" operations in the loop. I get about 50000 op/sec.
Add started a cluster with three geode nodes. I do get and put operations in the loop. I get the same 50000 op/sec.
I would expect to see the increased performance, but it is suprisingly the same for 1-node cluster and 3-nodes cluster.
Could you please help. What are the possible settings to change in order to get horizontal scalability.
Thank you.
Well, you just got horizontal scalability for data storage at no loss of throughput :)
To horizontally scale your throughput, I think your workload was not enough to max-out the server. You need to start multiple clients (OR threads in a single client) against a single server until you do not see throughput increase by adding any new clients. At this point you start a new server. This new server should allow you to add more clients and horizontally scale your throughput.
You may find the ycsb benchmark useful, which allows you to start multiple threads in a client to perform operations.
