Hi, I'm doing some hardware benchmarks for Cassandra and trying to figure out what is the best setup with the hardware options I have.
I'm testing a single-node Cassandra with three different setups: - 1 HDD for commit log and 6 HDDs for data logs - 1 HDD for commit log and 1 HDDs for data logs - 1 HDD for commit log and data logs The load generator is more powerful in terms of CPU than the Cassandra server, so I'm able to saturate the server's CPU with just one load generator. So far I got really unexpected results. I got higher "op rate" for the setup with less HDDs, and even worse, with the setup with just one HDD. So my question is, what does it mean the "op rate" in the Results of cassandra-stress tool? Thanks in advance! -- Herbert Fischer
