Now that I was able to run two nodes...

Now that I was able to run two nodes on the same host, I loaded my data, and ran my "select" test.

I am looking at about 10 times performance degradation.

Is this normal?

Thanks,
Arkadiy

Arkadiy,

Be careful with your deployment.xml parameters if you are running multiple VoltDB processes on the same box. If you ran a "1 process on the server" test with 4 partitions per server, you should run a "2 processes on the server" with 2 partitions per server (1/2 the 1 process).

You are also consuming available CPU if you are running your client application on that same server.

Can you verify your benchmark configurations, rerun, and post your results? Also, provide specifics of the server including RAM amount/speed, CPU Details (model and quantity), etc.
