Microsoft’s ReFS File System Remains Inaccessible to Windows 11 Users

Microsoft's Resilient File System (ReFS) supports volumes up to 35 petabytes and offers robust data protection through checksums and continuous integrity checks, reducing the risk of data corruption. However, Windows 11 defaults to the NTFS file system, requiring users to use command-line tools to access ReFS features, which may deter average consumers. ReFS is primarily designed for Windows Server environments and has not gained popularity among general users. Testing shows that Windows 11 formats new drives as NTFS, making ReFS less accessible. ReFS can experience performance degradation on single-drive consumer PCs compared to NTFS and lacks features like file system compression, encryption, object IDs, and extended attributes, raising compatibility concerns. Microsoft has introduced the Agent Launchers framework for AI agent registration in Windows, amidst user backlash regarding the evolution of Windows into an "agentic OS." The Windows and Devices segment generated .3 billion in the last fiscal year, remaining flat over three years, while Gaming and LinkedIn generated higher revenues. Users have reported frequent feature changes and declining quality in Windows 11, with Microsoft's Controlled Feature Rollout system causing inconsistencies across devices. ReFS is accessible through the Dev Drive feature in Windows 11, which prioritizes performance over security. Microsoft faces competition from various fronts, including Valve's SteamOS, Apple's upcoming MacBook, and Google's Chrome OS, particularly in the education sector.

Windows 11 driver hack boosts NVMe SSD performance by up to 85%

Windows 11 has recently begun to unlock the full potential of NVMe SSDs through registry modifications that enable a pseudo driver injection, resulting in nearly double the random write performance in certain scenarios. A native NVMe driver was rolled out in a recent update to Windows Server 2025, but it is not enabled by default in consumer versions of Windows 11. Users can activate it through specific registry edits. Testing by users revealed significant enhancements in random read and write performance after implementing these changes, with one user noting an 85% improvement in random write speeds. However, caution is advised when making registry edits, as some users have experienced loss of access to their file systems, which was recoverable by reverting the changes. There is no official timeline for when Microsoft will make the native NVMe driver available for Windows 11.

Windows Moves To Agentic OS As Backlash Erupts

Microsoft's Windows chief, Pavan Davuluri, introduced the concept of an "agentic" operating system, which aims to integrate applications, cloud services, and devices for a more autonomous user experience. This vision has generated skepticism among users, who fear it may lead to intrusive AI interactions. The term "agentic" refers to systems capable of performing multi-step tasks on behalf of users, potentially enhancing integration with file systems, notifications, and cloud services. However, past experiences with intrusive advertisements and privacy concerns have led to a trust deficit among users. The introduction of such systems raises privacy and security issues, prompting regulatory scrutiny and calls for explicit permissions, human confirmation for significant actions, and robust local processing. Hardware manufacturers are investing in AI PCs to support these developments, while developers will have access to new APIs for application integration. Microsoft faces a messaging challenge in promoting this vision, needing to demonstrate clear benefits and prioritize user agency to alleviate concerns.

How to load test PostgreSQL database and not miss anything

Practitioners face challenges during load testing of Tantor Postgres databases using pgbench, primarily due to insufficient documentation of the testing environment, leading to non-representative results and the need for repeated tests. The pg_perfbench tool has been developed to address these issues by ensuring repeatability, safeguarding data, and simplifying result comparisons through a cohesive template. It automates pgbench execution, collects metadata about the testing environment, and generates structured reports. pgbench operates on a TPC-B model, providing performance metrics such as transactions per second (tps), average latency, and the number of processed and failed transactions. A Bash script can be used to automate pgbench tests with varying client numbers, logging results into separate files. The pg_perfbench tool captures extensive data regarding the database environment and generates reports that include system properties, common database information, benchmark details, and test results. It facilitates the comparison of multiple load test results and ensures that environments being compared are consistent in terms of PostgreSQL versions and system parameters. The tool also allows for the evaluation of performance impacts from changes to PostgreSQL settings by generating separate reports for different configurations. It verifies compliance of specified parameters before joining reports, ensuring accurate comparisons. The final reports are structured in JSON and HTML formats, enhancing analysis and collaboration efforts.
