PostgreSQL 9.6 High Performance

Overview of this book

<p>Database administrators and developers spend years learning techniques to configure their PostgreSQL database servers for optimal performance, mostly when they encounter performance issues. Scalability and high availability of the database solution is equally important these days. This book will show you how to configure new database installations and optimize existing database server installations using PostgreSQL 9.6.</p> <p>You will start with the basic concepts of database performance, because all successful database applications are destined to eventually run into issues when scaling up their performance. You will not only learn to optimize your database and queries for optimal performance, but also detect the real performance bottlenecks using PostgreSQL tools and some external tools. Next, you will learn how to benchmark your hardware and tune your operating system. Optimize your queries against the database with the help of right indexes, and monitor every layer, ranging from hardware to queries. Moving on, you will see how connection pooling, caching, partitioning, and replication will help you handle increasing database workloads.</p> <p>Achieving high database performance is not easy, but you can learn it by using the right guide—PostgreSQL 9.6 High Performance.</p>

Disk benchmarking tools


Now it's time to see some real disks measured. For the first few examples here, the drive being tested is a 320 GB Seagate Momentus 7200.4 3 Gbps SATA, model number ST9320423AS. This is one of the faster 2.5" laptop drives on the market, and its more detailed access-time specifications were given in the preceding IOPS section. The results shown are from an installation into a Lenovo ThinkPad T60 with an Intel Core 2 Duo T7200 running at 2.0 GHz.

We'll start with the HD Tune program running on Windows, because its graphs are extremely nice and it measures almost everything you'd hope for. Its graphs demonstrate several aspects of general disk performance more clearly than the command-line tools for UNIX systems covered in the following sections.

Basic disk benchmarking using HD Tune

A great tool for the sort of basic disk benchmarking needed for databases on Windows systems is HD Tune, available at http://www.hdtune.com/. The program is free for a trial period, with a...
