PostgreSQL performance tuning with SolarWinds tool helps you collect and analyze PostgreSQL configuration. From a unique “time slice” view layering VM metrics with database metrics to in-depth ESXi host metrics, DBAs are armed with the data they need to determine the impact on their PostgreSQL instance. Running the ANALYZE command updates these statistics so that Postgres has a fresh set of data about how to create its plans. You want to make sure that your applications aren’t unnecessarily connecting, as this can be costly and can impact performance. Plans are the steps that PostgreSQL is going to take to find requested data. USD 40/mo (USD .06/hr) 8 GB Benchmarking is the tool of choice for testing and tuning the performance of a relational database management system (RDBMS). With either choice, you win. So, now that we see how great logs are for understanding system performance, how do we go about setting them up or changing them? If you’re scanning your database sequentially (often called a table scan) for your data, your performance will scale linearly— more rows, slower performance. It's high time to turn to Query Profiler. Shared Buffers works in cooperation with operating system cache, rather than replacing it. These caches improve performance by reducing the physical I/O necessary. This article aims to help. PostgreSQL performance tuning is a complex task. When it comes to hardware updates, you should consider the following: Updating your memory. On the note of increasing memory, if you’re running your database application on the same server as your application, you may want to consider isolating it.
