The TimescaleDB team has released a new tool called `timescaledb-tune` that helps users tune and configure their PostgreSQL instances to leverage their existing hardware for better performance. The tool simplifies the process of configuring reasonable settings for memory, parallelism, WAL, and other parameters, making it easier for users to achieve good performance out of the box. By using `timescaledb-tune`, users can guide themselves through a series of prompts to configure their database for optimal performance, reducing the need for manual configuration and minimizing the risk of underutilizing hardware resources. The tool has been tested on larger cloud VMs and shown significant improvements in write and read performance, with average write performance improving by 1M metrics per second and query performance improving by roughly 3x when using the tuned settings.
