Benchmark PostgreSQL With Linux HugePages

Linux kernel provides a wide range of configuration options that can affect performance. It’s all about getting the right configuration for your application and workload. Just like any other database, PostgreSQL relies on the Linux kernel to be optimally configured. Poorly configured parameters can result in poor performance. Therefore, it is important that you benchmark database performance after each tuning session to avoid performance degradation. In one of my previous posts, Tune Linux Kernel Parameters For PostgreSQL Optimization, I described some of the most useful Linux kernel parameters and how those may help you improve database performance. Now I am going to share my benchmark results with you after configuring Linux Huge Page with different PostgreSQL workload. I have performed a comprehensive set of benchmarks for many different PostgreSQL load sizes and different number concurrent clients.
