Improving Lakebase Postgres compute cache

Lakebase Postgres employs a disaggregated storage model that enhances data management through efficient caching, utilizing an object store like S3 for backups. The caching operates on two layers: within distributed storage for optimizing write and read performance, and on the Postgres compute side for ultra-fast access to frequently accessed pages. Traditional Postgres caching involves shared buffers and the OS page cache, which leads to double buffering and inefficiencies. Lakebase Postgres addresses these issues by implementing a local file cache (LFC) and larger shared buffers, allowing for more effective memory utilization without the drawbacks of the OS page cache. The shared buffers are set to a maximum of 1 GB, while the LFC can utilize up to 75% of DRAM. The introduction of huge pages reduces memory management overhead and improves performance, resulting in significant throughput increases and reduced latency in production environments. Recent enhancements have shown up to 2× throughput improvements and substantial reductions in CPU usage. The focus is now on extending these benefits to autoscaling Postgres computes, with plans to implement dynamic shared buffers and autoscaling huge pages.

Autoscaling Lakebase Postgres

Choosing a database instance size without prior knowledge of the workload can lead to inefficiencies and excessive compute usage. Lakebase Postgres addresses this with an autoscaling feature that eliminates manual sizing, utilizing in-place VM resizing and a monitoring algorithm for CPU, memory, and working set size. Lakebase Postgres separates compute and storage layers, allowing independent resizing of compute nodes without affecting the database. The autoscaling algorithm relies on three signals: CPU load (cpuGoalCU), memory use (memGoalCU), and compute-cache working set size (lfcGoalCU). The CPU load is monitored every five seconds, aiming to maintain it at or below 90% capacity. Memory usage is tracked at two frequencies: overall memory every five seconds and Postgres-specific memory every 100 milliseconds, with a goal to keep usage below 75% of allocated RAM. The compute cache evaluates active data access efficiency, adjusting size based on workload. The working set is estimated using a modified HyperLogLog algorithm that records timestamps for page accesses, allowing for distinct page estimates over various time frames. The algorithm projects future working-set growth to allocate sufficient cache while capping it at 75% of RAM. Resizing the compute involves four components: the autoscaler-agent, vm-monitor, Kubernetes scheduler, and NeonVM. Scaling up occurs when any of the three goals indicate a need for more resources, while scaling down includes verification to ensure sufficient memory remains for operations. Timely adjustments in both directions are prioritized to minimize costs.

Windows Search still can’t find half my files, because Microsoft fixed the wrong part

Windows 11's native Search feature has been improved with a new indexing system that automatically indexes frequently accessed folders. The latest build, 26100.9267, allows search results to appear after two keystrokes and is more forgiving of typographical errors. Users can choose between web or store suggestions. However, issues persist, such as files remaining invisible in indexed folders. Users have two indexing options: Classic mode, which covers limited locations, and Enhanced mode, which indexes all partitions but may affect battery life and CPU usage. Many users prefer third-party alternatives like Everything, which indexes files directly from the NTFS Master File Table without requiring mode selection. Despite improvements, the overall search experience in Windows remains unsatisfactory.

Microsoft explains why Pinball vanished from Windows: “We couldn’t afford to spend days studying the code”

3D Pinball was a space-themed game included in Windows XP since its debut in 1995. It was removed with the launch of Windows Vista due to a bug in the code that caused the game to be unplayable, not because of legal issues as commonly believed. The bug occurred during the transition of Windows XP to 64-bit architecture, where the ball would drop into the launcher and fall through the plunger. Microsoft engineer Raymond Chen, who worked on the project, noted that the original code was largely undocumented, making it difficult to fix. The game was licensed from Cinematronics and Maxis, which limited Microsoft's rights to bundling it within Windows and its Plus! packs, preventing a standalone release. Attempts to revive the game were hindered by these legal constraints. As of 2022, no official version of 3D Pinball has been included in Windows 11, and the licensing situation remains complicated due to the acquisition of Cinematronics and Maxis by Electronic Arts.

A cracked version of Marvel Tōkon is reigniting questions around DRM and its impact on PC games

Marvel Tōkon: Fighting Souls has faced significant criticism since its PC release due to performance issues, including stuttering frame rates and network problems. A patch was issued, but many players still experienced difficulties. The console version has not encountered these issues, leading to speculation that the DRM in the Steam version may be causing high CPU usage. A cracked, DRM-free version has emerged, reportedly offering better performance, with players noting it is less taxing on CPUs and runs smoothly even on lower-end hardware. Social media has highlighted a nearly 40 FPS difference between the two versions. Concurrent player counts on Steam have dropped from a peak of 24,498 to 5,249 shortly after launch, as some players turn to the cracked version, which does not support online matchmaking. This situation raises concerns about the impact of DRM on gaming performance and could affect PC sales and the overall player base. The Marvel Tōkon social media account has indicated that further fixes for the PC version are forthcoming, but inquiries to Sony remain unanswered.
