One-click Postgres Pro optimization with pgpro_tune

pgpro_tune is a command-line utility designed to optimize the initial server configuration of Postgres Pro based on hardware specifications. It scans the server to identify key hardware details, processes these values through shell scripts that encapsulate tuning expertise, and generates recommended parameters for PostgreSQL settings, including memory management, autovacuum tuning, connection limits, and statistics collection. The utility appends these settings to the postgresql.conf file, ensuring they override the default settings. pgpro_tune supports various presets for different use cases and allows database administrators to create custom presets. It runs automatically during cluster initialization and can be executed manually at any time, applying changes through standard PostgreSQL methods. This tool aims to streamline the tuning process, reduce the risks of misconfiguration, and enhance performance without replacing the need for advanced tuning in specialized scenarios.

PC gaming can’t stop getting Ws, as Microsoft shares it’s being weighed down by console and hardware revenue woes

Gaming revenue increased by 5% (6% when adjusted for currency), while Xbox content and services revenue grew by 8%. However, Xbox hardware revenue declined by 6% (5% CC) and experienced a 30% drop between early 2024 and early 2023. Microsoft has acquired game studios, including Blizzard and Bethesda, but faces challenges such as layoffs and a lack of compelling console exclusives. Current standout titles on Xbox Game Pass do not require an Xbox purchase, reflecting a trend where console exclusivity is becoming less relevant, except for Nintendo.
