The PostgreSQL buffer is called shared_buffer which is the most effective tunable parameter for most operating systems. It’s low because certain machines and operating systems do not support higher values. Plus another recent post on benchmarks: Tuning PostgreSQL for sysbench-tpcc. wal_buffers. Related posts.

Looking across a set of eight Java benchmarks, we find that only two of them are array dominated, the rest having between 40% to 75% of the heap footprint allocated to objects, the vast majority of which are small. Consider a B-Tree node from the B-tree Java benchmark: Uncompressed, it’s memory layout looks like (a) below. Evaluation.

PostgreSQL performance optimization is an ongoing process involving monitoring, benchmarking, and adjustments to maintain high-performing PostgreSQL databases. The PostgreSQL buffer is called shared_buffer, which is the most effective tunable parameter for most operating systems. Why is PostgreSQL performance tuning important?

When you own all of the code then this may involve some back of the envelope estimates, competitive benchmarking, or intuition tuned by experience.

Another big jump, but now it was my job to run benchmarks in the lab, and write white papers that explained the new products to the world, as they were launched. I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R.
