Hello Viktor, The benchmarks you're referring to are real and list all the configuration parameters as well as the source code. No cheating.
The first catchy difference between your and those benchmarks is that you're using TRANSACTIONAL mode for Ignite. This involves a 2-phase-commit protocol making TRANSACTIONAL gets slower than ATOMIC gets. Plus, if there is a chance your benchmark queries similar keys in parallel then some of the Threads will be blocked until the locked keys are released. So, check for ATOMIC caches or, to make benchmark fair, use lightweight transactions of Cassandra. Also, I would look into the following areas: - Share your Cassandra and Ignite configurations and the source code for further analysis. Please also share your Ignite version. - Ensure GC, JVM and OS are fine-tuned and don't affect the performance: https://www.gridgain.com/docs/latest/perf-troubleshooting-guide/memory-tuning#java-heap-and-gc-tuning - Collect GC logs and use Flight Recorder for both the client and servers if the performance doesn't improve (it might be even a network latency): https://www.gridgain.com/docs/latest/perf-troubleshooting-guide/troubleshooting#debugging-gc-issues - Once the 3 servers cluster is fully optimized you might need to scale to 4 or 5 to achieve 500k+ queries. - Denis On Tue, Nov 26, 2019 at 3:00 PM Victor <vicky...@gmail.com> wrote: > It's 500k unique gets, spread across multiple threads.
