Microsoft’s new Outlook takes 10 seconds to do what Outlook Classic does instantly on Windows

Microsoft's Outlook for Windows is facing criticism for its notification handling, particularly in the new Outlook version built on the WebView2 framework. Users experience a delay of approximately 10 seconds when clicking on email notifications, compared to the near-instantaneous access provided by Outlook Classic, which allows users to open new emails in about five seconds. The new Outlook consumes significantly more memory and CPU resources, using between 490 MB and 636 MB of RAM, while Outlook Classic operates within 117 MB to 148 MB. Despite updates aimed at improving the new Outlook, the core issue of notification handling remains unresolved. Microsoft is working on enhancements, but the performance limitations of the WebView2 architecture continue to affect user experience. Outlook Classic will continue to be supported until April 2029.

WhatsApp is eating 1.2GB RAM on Windows 11, even as Microsoft kills web app slop

WhatsApp for Windows, despite having a large user base of 3 billion globally and 1.6 billion on Windows, suffers from significant performance issues, including high RAM usage (400 MB before logging in and up to 1.2 GB while idling), slow message delivery, and a choppy scrolling experience. The app operates as a web wrapper using the WebView2 framework, which leads to inefficient resource consumption compared to native applications. Users across various hardware configurations report freezing, delayed messages, and instability. Microsoft’s Teams app also faces similar performance challenges due to its reliance on the same framework. There is a growing concern about the trend of developers opting for web applications over native ones, driven by a lack of trust in native frameworks. Despite Microsoft's push for native app development through WinUI, there is currently no native version of WhatsApp for Windows, while Meta has developed optimized versions for other platforms.

Microsoft aims to speed Windows with ‘leap forward’ in WinUI 3 perf

Microsoft has announced a 25 percent improvement in the performance of WinUI 3, specifically in File Explorer components. There has been a 41 percent reduction in memory allocations and a 45 percent decrease in function calls. Some optimizations may involve breaking changes, which will initially be optional for developers. The enhancements are intended to become the default in future iterations of WinUI and the Windows App SDK. Despite these improvements, developers have expressed concerns about WinUI 3's performance, noting it is slower than WPF and UWP. The reliance on WinRT interop for component actions is seen as a significant factor hindering speed. Additionally, there are historical tensions regarding the adoption of Microsoft's frameworks within the Windows and Office teams, leading to skepticism about their reliability.

Databricks boosts Postgres writes 5x

Databricks has enhanced its managed Postgres service using lakebase architecture, achieving write throughput improvements of up to five times. Traditional Postgres durability mechanisms, such as full page writes (FPW), impose overhead that can inflate Write-Ahead Log (WAL) volume by up to 15 times in write-heavy scenarios. The lakebase architecture decouples compute from storage, allowing compute nodes to stream WAL records to a distributed quorum of safekeepers, mitigating the risk of torn pages. Databricks has addressed read performance challenges by transferring image generation to the storage layer, which reconstructs data pages by identifying the latest materialized image and replaying corresponding WAL deltas. This results in a 94% reduction in WAL traffic and significant performance enhancements, with write throughput increasing by over 4.5 times on a 32-vCPU instance and WAL generation decreasing from 58KB per transaction to under 4KB. In production settings, steady-state WAL generation dropped from 30 MB/s to 1 MB/s, and read latencies improved by 30% to 50%. The optimization has been seamlessly integrated across Databricks' Serverless and Neon databases without requiring restarts or interruptions for customers.

Microsoft vows to make Windows 11’s File Explorer much faster — and it’s about time

Microsoft is enhancing the performance of File Explorer in Windows 11, moving beyond the initial preloading feature introduced last year. Tali Roth, Microsoft's Head of Product for Windows Shell, stated that the company is committed to implementing targeted optimizations to improve the speed and responsiveness of File Explorer. The preloading adjustment improved the app's launch time but did not resolve performance issues during subsequent uses, as users reported sluggishness when navigating folders. Microsoft's new strategy involves deeper foundational engineering to reduce unnecessary disk reads and application hangs. The ongoing "fix Windows 11" campaign indicates progress, though questions remain about the initial performance issues.

Ring’s Billion-Scale Semantic Video Search with Amazon RDS for PostgreSQL and pgvector

Users of Ring's semantic video search can quickly find specific moments in video data, such as "a dog in my backyard" or "a package delivery," using a system that employs PostgreSQL and pgvector for video data handling. The system utilizes vector embeddings to represent visual content, allowing for efficient storage and similarity searches. When a user queries a term, the system converts it into a vector to retrieve similar video frames in under two seconds. Ring's video search operates on a global scale, processing billions of read requests daily across four continents and nine AWS regions, with strict latency requirements for millions of users. Key metrics include storing 100–200 billion embeddings, generating approximately 2 billion new embeddings daily, and maintaining a data footprint of 140–150+ TB across three PostgreSQL clusters.

Intel VP claims up to 30% of CPU performance is untapped by modern games — software optimization is critical to unlocking full potential of hybrid CPUs

Intel's transition to a hybrid architecture for its CPUs began with the Alder Lake series in 2021, combining performance and efficiency cores. Intel's Vice President, Robert Hallock, noted that while the hybrid architecture has matured, a "unified core" is still in development. He mentioned that many users disable efficiency cores (E-cores) to enhance performance, but the performance difference between using only performance cores (P-cores) and both types of cores is minimal, around 1%. Hallock explained that early implementation of Intel's Thread Director improved performance with only P-cores, and the Windows task scheduler struggles without it. He emphasized the importance of software optimization for enhancing performance, stating that a significant portion of potential performance—estimated between 10% to 30%—remains untapped due to suboptimal game optimization. AMD's approach includes integrating additional SRAM through its 3D V-cache technology, while Intel's upcoming Nova Lake will introduce a Big Last Level Cache (bLLC). Hallock indicated that developers have primarily optimized for AMD's silicon, limiting the full potential of Intel's hybrid architecture.

Nvidia’s ‘new’ budget gaming GPU has 12GB VRAM, arrives in June, according to leak

The Nvidia GeForce RTX 3060 may return to retail by June, following leaks about Nvidia's GPU production plans. Production of the GA106 GPU has resumed at Samsung, as current-generation GPUs are primarily made by TSMC, which is at full capacity. The RTX 3060 is expected to be priced between the RTX 5060 and RTX 5050, featuring 12GB of GDDR6 VRAM, more than both the RTX 5060 and RTX 5050. The anticipated launch of a new RTX 5050 with 9GB of VRAM may be delayed or canceled. The RTX 3060 will support DLSS upscaling but not frame generation.

This ‘highly realistic’ city-builder could be the first real competition Cities: Skylines has seen in over a decade

City Masterplan is a newly unveiled metropolis simulator that offers expansive environmental canvases measuring 24x24 km, allowing players to design urban landscapes in various architectural styles. The game features a visual aesthetic similar to Cities: Skylines 2, with realistic skies, dynamic lighting, and immersive weather conditions. It is built on the Unreal Engine, which may present performance challenges. As Cities: Skylines approaches its twelfth anniversary, there is a demand for a fresh city-building experience, with City Masterplan potentially revitalizing the genre. There is no official release date, but speculation suggests a launch not before 2027.
