PostgreSQL performance optimization aims to improve the efficiency of a PostgreSQL database system by adjusting configurations and implementing best practices to identify and resolve bottlenecks, improve query speed, and maximize database throughput and responsiveness. What is PostgreSQL performance tuning?

HammerDB is a load testing and benchmarking application for relational databases. On high-performance multi-core systems all the supported databases can return performance in the many millions of transactions per minute. Basic Benchmarking Concepts. To benchmark a database we introduce the concept of a Virtual User.

HammerDB is a software application for database benchmarking. HammerDB has graphical and command line interfaces for the Windows and Linux operating systems. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. Why HammerDB was developed. The NOPM Metric.

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.

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.

When you own all of the code then this may involve some back of the envelope estimates, competitive benchmarking, or intuition tuned by experience. When dealing with a closed box like Microsoft’s NTFS file system it’s trickier to know if things could be running faster than they are. You know where to find me.

Version7 (Future): Move all compute to the public cloud, carve out more services for impact isolation, dynamic resource pooling to manage pets and cattle efficiently. Which languages do you use to develop your system? Java/Python mostly and some small services in Go/C. What operating systems do you use?
