Windows operating systems have numerous background services that can consume system resources and slow down performance. Users can improve responsiveness by disabling non-essential services. 1. Windows Search: Indexes files and data for quick searches; can tax CPU and RAM. To disable: press Ctrl + R, type services.msc, locate Windows Search, stop the service, and set Startup type to Disabled or Manual. 2. SysMain (formerly Superfetch): Preloads frequently used applications into memory but can lead to unnecessary disk activity on SSDs. To disable: access services.msc, find SysMain, stop the service, and set Startup Type to Disabled. 3. Windows Update Delivery Optimization: Shares update files with other PCs, consuming bandwidth. To disable: go to Settings -> Windows Update -> Advanced Options and turn it off. 4. Remote Desktop Services: Enables remote connections, which can drain resources and pose security risks. To disable: locate Remote Desktop Services in services.msc, stop it, and set Startup type to Disabled. 5. Connected User Experiences and Telemetry: Collects usage data and can transmit sensitive information. To disable: turn off the service and navigate to Settings -> Privacy & Security -> Diagnostics & Feedback to disable Diagnostic data. Additional services that may be disabled include Print Spooler, Fax, Bluetooth Support, and Windows Error Reporting Service for further performance optimization.

Windows 11 includes features to enhance productivity, particularly through customization for older PCs. Key strategies include: 1. Virtual Desktops: Use Win + Tab or the Task View icon to create separate virtual desktops for work, allowing for a more organized workspace. Applications can be dragged into this desktop and will reappear upon reopening. 2. Focus Sessions: Activate Focus via Settings -> System -> Focus to set timers for work sessions and breaks, enabling Do Not Disturb mode to silence notifications during work periods. 3. System Optimization: Select a High Performance power plan in Control Panel -> Power Options or Settings -> System -> Power & battery, and disable unnecessary startup apps in Task Manager to improve performance. 4. Pinning Apps and Snap Layouts: Pin frequently used applications to the taskbar for quick access and use Snap Layouts by dragging windows to the screen edges for efficient arrangement. 5. Keyboard Shortcuts: Utilize essential Windows 11 shortcuts to enhance efficiency, such as Windows key + A for Quick Settings, Windows key + E for File Explorer, and Windows key + H for voice typing.

PostgreSQL is an open-source relational database management system known for its extensibility, which allows developers to enhance its capabilities through various extensions and plugins. The pgstattuple extension provides detailed statistics at the tuple level from PostgreSQL tables and indexes, revealing key metrics such as the number of live tuples, dead tuples, average length of live tuples, total free space, and percentages of free space and dead tuples. These metrics help database administrators identify potential health and performance issues, such as excessive table bloat or index fragmentation. Both Amazon Aurora and Amazon RDS support the pgstattuple extension, which can be activated using the command CREATE EXTENSION pgstattuple;. Functions like pgstattuple(relation) and pgstatindex(index) can be used to analyze physical storage and index statistics. Bloat occurs when unused space is left behind after UPDATE and DELETE operations, and the autovacuum process in PostgreSQL automates the cleanup of dead tuples. However, if autovacuum fails, manual intervention may be necessary. Regular monitoring of bloat is essential for maintaining performance, and metrics from pgstattuple can help optimize autovacuum settings. The pg_cron extension can automate VACUUM operations to manage bloat proactively. Index bloat can also be detected using pgstatindex, and significantly bloated indexes can be rebuilt using REINDEX or pg_repack. Best practices for using pgstattuple include estimating bloat with check_postgres, analyzing physical storage, monitoring dead_tuple_percent, and avoiding interference on highly active tables.

Windows 11 is developing a new FAQ section in the Settings app that provides advice on optimizing system performance. This section, currently hidden and accessible via command line, includes guidance on whether a GPU is sufficient for high-end gaming, recommending a discrete graphics card with more than 4GB of RAM. It also states that 4-8GB of RAM is adequate for basic tasks like web browsing and document editing. Microsoft has not officially commented on this feature, and it remains unclear if it will be included in the next major update or only appear when hardware limitations are detected.

To optimize your Windows computer's performance, ensure your operating system is fully updated. If updates are current, utilize built-in utilities to reclaim disk space. For Windows 11, access "Cleanup recommendations" by clicking the Start button, selecting Settings, navigating to System, and then Storage. This feature lists temporary files in your Downloads folder and Recycle Bin, which can be deleted to free up space. It also recommends removing large or unused files. Use the Disk Cleanup utility by searching for "Disk Cleanup" in the search bar to identify and delete temporary internet files, setup log files, and cache files. To clear your PC's location cache, go to Settings, select Privacy and Security, scroll to "Location history," and click "Clear." To flush the DNS cache, press the Windows key + R, type ipconfig/flushdns, and press Enter. Regular file management and cleanup can significantly enhance system performance over time.

Proxima integrates connection pooling, query proxying, and load balancing into the Postgres Pro Enterprise DBMS, enhancing efficiency and minimizing latency. It establishes multiple connections for client sessions, optimizes resource usage, and alleviates server burdens. Proxima redirects client queries to the leader node in a BiHA cluster, automating cluster topology management. Load balancing is under development to prevent overload on replicas. The pgpro_queue extension facilitates asynchronous message processing directly within the database, ensuring transactionality, prioritization, filtering, and reliable message storage. Postgres Pro 17 Enterprise introduces enhanced query plan management tools, including the pgpro_multiplan extension for storing multiple execution plans and a query registration assistant for managing queries. Adaptive Query Execution (AQE) and Adaptive Query Optimization (AQO Enterprise) improve complex query execution by dynamically rescheduling long-running queries and correcting planner errors based on execution history. Security enhancements include the pgpro_usage extension for tracking database object usage and identifying unnecessary access rights. The pgpro_ilm extension automates storage optimization by relocating rarely accessed data and compressing it. Infrastructure improvements include BiHA enhancements, multimaster support, and improved management of partitioned tables, along with the updated PPEM 2.0 for better UI and automatic instance tuning.
