Troubleshoot RDS PostgreSQL High CPU Utilization

Vetrivel presents a guide on troubleshooting high CPU utilization in Amazon RDS and Amazon Aurora PostgreSQL-Compatible databases, focusing on three primary techniques to identify CPU spikes: 1. **Amazon CloudWatch**: Provides real-time monitoring and operational data to visualize CPU utilization trends and identify anomalies. 2. **Enhanced Monitoring**: Offers deeper insights into performance metrics for a more granular analysis of CPU usage. 3. **Database Engine Insights**: Allows diagnosis of performance issues directly through the database engine for better workload management. The video is segmented into chapters for easy navigation, covering the methods in detail.

Windows Server 2025 gains native NVMe support, 14 years after its introduction — groundbreaking I/O stack drops SCSI emulation limitations for massive throughput and CPU efficiency gains

Windows Server 2025 now supports native NVMe I/O, moving away from SCSI bus commands. This feature requires a registry key modification or group policy MSI to activate. Users can see performance improvements of up to 80% in IOPS and a 45% reduction in CPU utilization during high I/O loads. Testing on a two-socket Intel system with 208 logical cores and a Solidigm D7-PS1010 SSD showed a 45% increase in IOPS with one thread, 78% with eight threads, and 71% with 16 threads, alongside a 41% and 47% decrease in CPU load during 4K random reads with eight and 16 threads, respectively. The I/O processing workflow has been redesigned for better performance, enhancing overall latency and responsiveness. Community feedback is mixed, with some users experiencing negligible differences and others suggesting that only PCIe 5.0 NVMe devices can fully utilize the new I/O stack. There is no timeline for this feature's rollout to Windows 11, and its effectiveness may vary based on drive firmware quality. Home computing tasks may not see significant improvements, but multitasking and gaming experiences could benefit from reduced CPU load and improved system responsiveness.

Improve Aurora PostgreSQL throughput by up to 165% and price-performance ratio by up to 120% using Optimized Reads on AWS Graviton4-based R8gd instances

AWS has introduced Graviton4-based R8gd instances for Amazon Aurora, which offer significant performance enhancements over Graviton2-based db.r6g instances. Users can expect up to 165% higher throughput, a 120% improvement in price-performance ratio, and an 80% enhancement in application response time. The integration of an Optimized Reads-enabled tiered cache allows for expanded database caching capacity, minimizing network storage access and improving query response times. Organizations like Mindbody and Claroty have reported substantial performance improvements and cost savings after implementing these features. Aurora PostgreSQL 17 has introduced smarter storage batching algorithms and optimized writes, further enhancing performance for I/O-intensive applications. The db.r8gd instances allow for scaling up to 48xl, providing 192 vCPUs, 50 Gigabits of network bandwidth, and 10.4 TiB of local NVMe capacity. The benchmark testing using HammerDB demonstrated significant improvements in throughput, price-performance ratio, and response times when upgrading from db.r6g to db.r8gd instances. The Aurora Optimized Reads-enabled tiered cache is available for Aurora PostgreSQL versions 17.4 and higher, among others.

Windows Server 2025 Gets Native NVMe SSD Support After 12 Years

Microsoft has introduced native NVMe SSD support in Windows Server 2025 as an opt-in feature, marking a significant advancement 12 years after NVMe's inception. This new support allows direct multi-queue access to hardware, delivering up to 3.3 million IOPS on PCIe Gen 5 SSDs and over 10 million IOPS on Host Bus Adapters, while significantly reducing latency. The previous reliance on converting NVMe commands to SCSI commands caused processing latency and overhead. Native NVMe support eliminates outdated translation layers, enhances CPU utilization, and unlocks next-generation storage capabilities. Microsoft has set up an email address, nativenvme@microsoft.com, for user feedback and inquiries. There is no current information on the timeline for native NVMe support in Windows 11.

Amazon Aurora makes PostgreSQL Serverless generally available

The PostgreSQL-compatible edition of Aurora Serverless is now generally available, allowing users to create database instances that operate only when necessary and automatically adjust capacity based on demand. Customers are billed on a per-second basis for active database capacity and standard Aurora storage costs. Users can specify minimum and maximum capacity when creating a database, and the architecture separates storage from computational resources, allowing automatic scaling from a minimum of 10GB to a maximum of 64 TB. Aurora Serverless PostgreSQL is accessible in regions including US East (N. Virginia and Ohio), US West (Oregon), EU (Ireland), and Asia Pacific (Tokyo).

AI-powered tuning tools for Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL databases: PI Reporter

AWS offers services like Amazon CloudWatch and CloudWatch Database Insights for monitoring Amazon RDS performance metrics. Users can create custom dashboards for Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL-Compatible Edition. Essential metrics to monitor include Database Connections, CPU Utilization, Freeable Memory, and various I/O metrics. PI Reporter is an open-source tool designed to capture performance metrics and workload snapshots for Amazon Aurora PostgreSQL-Compatible Edition. It integrates with Amazon Bedrock to analyze data and provide actionable recommendations. Users can generate detailed HTML reports comparing performance metrics over time, assess workload changes, and identify performance issues. To use PI Reporter, prerequisites include enabling Amazon CloudWatch Database Insights and the pg_stat_statements extension. Installation involves cloning the repository, configuring IAM policies, and executing commands to create snapshots and reports. The tool is designed for ease of use and can be run on Amazon EC2 or on-premises. The report generated by PI Reporter includes a summary of findings, root causes, and recommendations for performance improvement. It also identifies resource utilization issues during specific operations, such as bulk data inserts or idle transactions. Users are advised to validate AI-generated recommendations with database experts and to monitor for idle transactions to optimize performance. Costs may be incurred from resources created by Amazon Bedrock, and users should clean up these resources when no longer needed.

Monster Hunter Wilds’ PC performance patches will keep coming, if almost as slowly as the game still runs

Capcom is facing ongoing challenges with the PC performance of Monster Hunter Wilds, despite multiple patches aimed at improving framerate stability. The company has committed to providing performance and stability updates until at least Winter 2025, with significant improvements expected by then. Game director Yuya Tokuda announced that the upcoming version 1.021 update will not include major performance enhancements, while the Title Update 4, scheduled between November and January, will focus on reducing CPU load. This is part of a two-phase optimization plan that will also address GPU load in future patches. Despite minor improvements, the game still struggles to perform well on high-end graphics cards, and previous solutions have been seen as ineffective. Tokuda suggested that players may need to adjust their graphics settings to better manage frame rates based on their hardware capabilities.
