Hardware Memory The amount of RAM to be provisioned for database servers can vary greatly depending on the size of the database and the specific requirements of the company. Benchmark before you decide. The optimal value can be decided after testing multiple settings, starting from eight is a good choice. I hope this helps!

For the rest of us, if you really need that extra performance (maybe what you get out-of-the-box or with minimal tuning is good enough for your use case) then you can upgrade hardware and/or pay for a commercial license of a tuned distributed (RHEL). This causes average slowdowns of 66% across the select , poll , and epoll tests.
