Experience of using PostgreSQL + 1C in companies with zero database competence

1. quiet exploitation (no incidents, critical falls, etc.) of PostgreSQL; 2. Flexible setup and operation; 3. No support specialist needed; 4. Database over 100 GB; 5. Automatic backup and recovery; 6. Fears and work with objections.

Tune your Linux Box, not just PostgreSQL

PostgreSQL is one of the leading open-source databases. Out of the box, the default PostgreSQL configuration is not tuned for any particular workload. The default configuration is designed in such a way that PostgreSQL can run on any system using minimum resources. Consequently, a default installation of PostgreSQL does not give optimum performance on high performance machine because it is set up to use all available resources. PostgreSQL provides mechanisms that allow you to tune your database according to your workload and machine specification. Outside of PostgreSQL, though, we can tune the Linux kernel to allow the database load to work optimally. In this talk, we will learn how to tune some of the PostgreSQL’s parameters, and we will see the effect of that tuning, but we will focus on demonstrating how to tune Linux for better postgres performance. As there are so many Linux kernel parameters that can be tuned to improve the performance of PostgreSQL, I will also share the results of benchmarks obtained when tuning some of the Linux parameters.
