Benchmarking is a way of discovering the performance of your infrastructure. Sysbench is a great tool to benchmark PostgreSQL servers. In this blog post, we’ll show you how to generate test loads using sysbench. We will make use of a two-node master-slave streaming replication setup byClust...
At this point PostgreSQL is already doing considerably more than 2M PostgreSQL TPM and 1M NOPM so the scability is already incredibly good. However it is clear that adding CPU resource beyond this point will only result in more time spent waiting in locking and will not improve p...
Once a connection in PostgreSQL is created, it can perform various operations that lead to changes in states. Based on the state and the time the connection has been in that state, an informed decision can be made as to whether the connection is active or has been left idle/abandoned. It...

MySQL, PostgreSQL, MongoDB, and the servers on which they run. PMM’s Query Analytics tool helps you quickly locate costly and slow-running queries so you can quickly address bottlenecks impacting performance. And remember that Percona engineers are always available to help you when you get ...
analysis of a database you run on your laptop. When testing some app, your local instance probably has 1/1000 the amount of realistic data compared to a production server. Or, you're running a bunch of end-to-end integration tests whose PostgreSQL performance doesn't make sense to measure...
setting up a PostgreSQL database instead of using the default SQLite database. You’ll configure the Gunicorn application server to interface with your applications. You will then set up Nginx to reverse proxy to Gunicorn, giving you access to its security and performance features ...
