I am already working on concurrency level improvement as well, this was done for single query execution as we are trying to make single queries execute much faster. As we can see in the attached results there is an improvement in almost all the queries so the expectation was that in concurrent queries also it will improve. Are you running the same queries concurrently or different queries and can you also tell me how you are running these queries concurrently.
