Why Postgres wants NVMe on the hot path, and S3 everywhere else

Efforts to merge storage roles into a single solution are ongoing, particularly with Amazon S3's durability and cost-effectiveness. In PostgreSQL, achieving a durable commit requires flushing the Write-Ahead Log (WAL) before signaling transaction completion, which can take tens of microseconds on high-performance NVMe drives but extend to milliseconds on slower storage. This latency impacts Online Transaction Processing (OLTP) systems and user response times. Benchmark studies show that systems with faster local storage outperform those with slower alternatives as workloads exceed memory capacity. The fsync operation in PostgreSQL is a commitment rather than a simple write, with enterprise-grade SSDs performing better due to power-loss protection. Read operations also face challenges, as PostgreSQL's need for small, latency-sensitive reads conflicts with S3's design for larger, higher-latency requests. As the working set exceeds memory, storage latency becomes a critical performance factor. Modern managed PostgreSQL systems typically do not place object storage in the critical commit path, instead maintaining a fast log or cache close to the database while relegating colder data to remote storage. Recent PostgreSQL developments, such as asynchronous I/O support in version 18, aim to leverage fast storage more effectively. S3 is valuable for tasks like WAL archiving and backups, but these should be kept separate from the commit path to avoid resource contention. The solution involves using both NVMe and S3, with fast storage managing commits and cache misses, while object storage handles archives and backups. PostgreSQL performs best when hot and cold storage functions are clearly delineated.

Pragmata PC performance tested: 18 GPUs take us to the Moon

Capcom's new sci-fi shooter, Pragmata, features a narrative centered on Hugh, the last survivor of a lunar rescue mission, and Diana, an android with hacking abilities, as they navigate a 3D-printed lunar facility. The game has locked out Radeon support, which has raised concerns about business motivations over technical limitations, despite the Radeon RX 9000-series cards performing well. AMD users can access FSR 3 upscaling, with FSR 4 available for RX 9000-series cards, while older RX 7000- and RX 6000-series cards are limited to FSR 3. The game supports various rendering modes, including rasterization, ray tracing, and path tracing. At 1080p, ray tracing performs well on most hardware, but at 1440p and 4K, higher VRAM cards show better performance. Path tracing requires upscaling and frame generation for optimal playability, with DLSS Frame Generation providing significant benefits for Nvidia users. The RTX 3070 lacks DLSS frame generation support, necessitating FSR 3 for testing, which results in lower image quality compared to DLSS. Overall, Pragmata is designed to leverage advanced graphics technologies, particularly for GeForce RTX 40- and 50-series card owners, while also offering a solid experience for AMD users, albeit with some limitations.

Postgres to Iceberg in 13 minutes: How Supermetal compares to Flink, Kafka Connect, and Spark

Supermetal introduced Iceberg sink support, allowing for data transfer from Postgres to Iceberg. In a performance comparison, Supermetal completed snapshotting in 13 minutes, while Flink took 90 to 116 minutes, Kafka Connect required 120 minutes, and Spark exceeded 3 hours. The tests focused on throughput during the snapshotting phase rather than latency. The setup used the TPC-H dataset with a scale factor of 50 and involved AWS infrastructure. Supermetal operates independently of Kafka, enabling direct data delivery from source to sink. It utilizes a JSON configuration file for deployment, supporting various catalogs and advanced configuration options. Supermetal's Iceberg writer can adjust settings based on the CDC source phase. Throughout the tests, Supermetal maintained low CPU and memory usage, while other tools faced challenges with performance and resource management. Data synchronization was validated across all tools, with Supermetal achieving at least 7x faster snapshotting performance without tuning.

Connecting .NET Lambda to Amazon Aurora PostgreSQL via RDS Proxy

Many organizations are modernizing legacy .NET applications while reducing database costs and enhancing scalability, particularly during migrations to AWS Lambda and transitions from SQL Server to Amazon Aurora PostgreSQL-Compatible Edition. The process involves connecting Lambda functions to Aurora PostgreSQL using Amazon RDS Proxy, with AWS Secrets Manager managing secure credential storage. The architecture includes a .NET Lambda function interfacing with Aurora PostgreSQL via RDS Proxy, which provides connection pooling to minimize database connection overhead. The solution requires a CloudFormation template to provision resources such as a VPC with private subnets, an Aurora PostgreSQL cluster, RDS Proxy, and Secrets Manager. The RDS Proxy is configured with parameters including PostgreSQL engine family, idle client connection timeout, and Secrets Manager secret. A Windows EC2 instance is provisioned, and access is facilitated through AWS Systems Manager Fleet Manager. The solution includes creating a sample table named "employee" in the database and a new .NET Lambda project that utilizes Npgsql for database connections. The Lambda function is deployed using the AWS CLI, and testing involves invoking the function and retrieving logs from Amazon CloudWatch. Finally, resources created during the process should be deleted to prevent ongoing charges.

How to Profile Modern PC Games with NVIDIA Nsight Graphics

Performance analysis in PC gaming has become more complex with the introduction of DirectX 12 and Vulkan, incorporating technologies like asynchronous compute, hardware ray tracing, and machine learning-assisted denoising. Understanding GPU performance requires advanced tools to analyze workload distribution and shader behavior, with NVIDIA Nsight Graphics being a key resource. NVIDIA Nsight Graphics is a graphics debugger and profiler for modern graphics APIs, featuring the GPU Trace Profiler, which provides detailed insights into GPU execution and performance bottlenecks. Recent updates have improved its utility, including a Flame Graph for the Shader Profiler and support for NVIDIA's DLSS in D3D12 applications. The Peak-Performance-Percentage analysis method focuses on identifying GPU workload constraints and optimizing utilization rather than relying on assumptions about performance bottlenecks. This methodology is applied using Nsight Graphics to analyze GPU traces from the game Cyberpunk 2077, contrasting traditional rasterization with path tracing enhanced by DLSS Ray Reconstruction. The test setup included an Intel Core i7-14700K CPU, 32 GB RAM, and an NVIDIA GeForce RTX 4090 GPU, capturing two scenarios: one with raster-only settings and another with path tracing and DLSS. The analysis revealed that the rasterized frame's most costly aspect was lighting processing, while the path-traced frame showed increased total frame cost and a hybrid workload involving rasterization, ray traversal, and AI-driven processes. Key findings indicated that modern GPU performance is heavily influenced by memory behavior rather than just shader arithmetic, with significant time spent on compute-driven lighting processing and data movement. The analysis also highlighted that ray tracing performance is constrained by memory efficiency, indicating that performance does not scale linearly with RT-core throughput.

AWS Engineer Reports PostgreSQL Performance Halved By Linux 7.0, But A Fix May Not Be Easy

An engineer from Amazon/AWS reported a significant performance regression in PostgreSQL when running on the nearly finalized Linux 7.0 kernel, with throughput dropping to about half of previous kernel versions. The regression, observed on a Graviton4 server, is attributed to increased time spent in a user-space spinlock due to changes in preemption modes in Linux 7.0. A patch to revert to PREEMPT_NONE as the default preemption model has been submitted but may not be adopted. Peter Zijlstra suggested that PostgreSQL should adapt to utilize the Restartable Sequences (RSEQ) time slice extension to mitigate the performance drop. If this adaptation is accepted, the responsibility for the performance decline may shift to PostgreSQL, potentially affecting users until the database is updated. The stable release of Linux 7.0 is expected in about two weeks, coinciding with the launch of Ubuntu 26.04 LTS.
