Copilot Code Review Reaches Azure Repos, Billed Per Review with Reporting Two Days Behind
Microsoft now extends GitHub Copilot’s code review capabilities to Azure Repos, recognizing the need for flexibility within the Azure DevOps ecosystem. This expansion allows all Azure DevOps customers to leverage AI-powered code analysis without requiring a migration to GitHub. Reviews are billed per use via your Azure subscription, with cost visibility appearing in Cost Management approximately 48 hours later. Budget alerts will notify you of spending, and organizations are limited to five concurrent reviews.
Presentation: Instrumentation at Scale: Having Your Performance Cake and Eating It Too
Unlock full system visibility without performance compromise. Brian Martin, drawing on his experience at IOP Systems, presents "Instrumentation at Scale: Having Your Performance Cake and Eating It Too," exploring strategies for low-overhead instrumentation. Learn about atomic primitives, per-CPU sharding, and eBPF integration—critical techniques for software architects and engineering leaders. Discover how to maintain comprehensive insights without sacrificing speed. For deeper exploration of performance optimization, see our article, "This Python Library Can Run Pandas Workloads Up to 20x Faster."
Speculative Decoding on CPUs: Nearly 4x Faster Token Generation with DFlash
Unlock significantly faster token generation on your CPUs with DFlash, a novel speculative decoding technique. Our vLLM tests demonstrate a remarkable 3.92x increase in autoregressive throughput using Qwen3.5-9B on Intel Xeon 6 processors—effectively repurposing idle compute. This approach accelerates processing without altering model output. We detail the underlying performance gains, acceptance metrics, and factors influencing speculation’s effectiveness. Explore the full analysis in our post, and for broader context on the AI landscape, see our coverage of recent developments at Hugging Face.
PagedAttention vs. RadixAttention: Optimizing LLM KV Cache Management
Modern Large Language Models (LLMs) demand optimized Key-Value (KV) cache management to unlock peak performance. As context windows expand, GPU memory consumption becomes a critical bottleneck, impacting concurrency and latency. Two significant advancements address this challenge: PagedAttention refines memory allocation, while RadixAttention facilitates efficient prefix reuse. These techniques collectively enable substantial gains in LLM throughput. Explore the details of these breakthroughs and their impact on production LLMs in our full post, building upon insights from experiences like "The LLM Judge That Kept Agreeing With Itself."
Running SQL Concurrently Across Three Remote DuckDB Servers with Quack
Explore a novel approach to data processing with "Running SQL Concurrently Across Three Remote DuckDB Servers with Quack." This experiment demonstrates a practical application of remote SQL execution, empowering users to leverage distributed resources for enhanced performance. Discover how Quack facilitates this process, offering a streamlined solution for complex queries. For those interested in building applications that accumulate understanding, consider "Designing a Persistent Knowledge Layer That Refuses to Guess," which details a vendor-neutral blueprint for RAG systems.
Article: Virtual Threads After JDK 24: What Changed for Production Java
JDK 24 marked a significant shift for virtual threads in production Java, removing the carrier-thread pinning that previously impacted teams like Netflix. While this addressed one bottleneck, JDK 25 LTS introduces a new challenge: downstream-resource saturation. This article, by Sandeep Bharadwaj, maps the failure modes that arise after adopting virtual threads and provides a practical sequence for mitigation, supported by public benchmarks. Understand these changes to ensure optimal performance—consider exploring "How Much Does a Local LLM Actually Cost to Run?
Why Adding More AI Agents Made Our System Slower
Scaling AI agent systems isn’t always linear. We recently encountered a surprising bottleneck: asynchronous task management. As we expanded to hundreds of LLM agents, seemingly minor CPU tasks quietly became our largest performance constraint, slowing overall system speed. This post details how we identified and addressed this hidden cost, offering practical insights for anyone building complex AI workflows. Learn from our experience – a challenge we’ve explored further, alongside broader lessons from 8.5 years of machine learning.
Presentation: Compiling Workflows into Databases: The Architecture That Shouldn't Work (But Does)
Join Jeremy Edberg and Qian Li to discover a surprisingly effective architecture for durable AI workflow execution. Their presentation, "Compiling Workflows into Databases: The Architecture That Shouldn't Work (But Does)," reveals why external orchestrators often introduce reliability challenges and demonstrates how leveraging your existing database can provide a robust solution. DBOS Transact utilizes standard tables, SKIP LOCKED queues, and unique primary keys to achieve fault tolerance and minimal latency—all without the complexity of separate distributed systems.
Presentation: The Rust High Performance Talk You Did Not Expect
Gain a fresh perspective on high-performance development with Ruth Linehan’s presentation, "The Rust High Performance Talk You Did Not Expect." Linehan details a surprising shift: migrating high-performance caching services from Kotlin to Rust dramatically improved delivery speed and reduced engineering overhead. Discover how Rust's borrow checker and compile-time safety enhance developer workflows and optimize concurrent code—backed by practical examples using Criterion and flamegraphs.
