From hand-tuned Go to self-optimizing code: Building BitsEvolve

Datadog found that small Go-level optimizations can produce substantial infrastructure savings when applied to heavily used, autoscaled services. Manual work—such as removing bounds checks and prioritizing common input paths—delivered improvements ranging from 25% to over 90% in targeted functions. These successes also revealed the need to automate expert optimization techniques through systems like Datadog’s internal BitsEvolve. ## Finding Hotspots That Matter - Micro-optimizations are worthwhile when: - Functions run millions or billions of times. - Services are aggressively autoscaled, allowing CPU savings to reduce machine counts. - Resource usage drops measurably. - Datadog focused on high-throughput services processing timeseries tags and values. - Individual hotspots sometimes represented only 0.5% of compute, but repeated savings could add up to tens of thousands of dollars annually. - The broader goal was a 5–10% reduction in CPU usage across many improvements. ## Removing Bounds Checks from `NormalizeTag` - `NormalizeTag` called `isNormalizedASCIITag`, a frequently executed validator for ASCII tag strings. - AI coding tools suggested changes that were correct but produced no measurable performance gains. - Examining Go assembly with Compiler Explorer revealed two `runtime.panicBounds` calls per loop iteration. - Restructuring the loop eliminated unnecessary bounds checks and enabled further tuning. - The function became 25% faster, reducing service CPU usage by 0.75% and producing projected annual savings of tens of thousands of dollars. ## Using Observability to Optimize for Real Inputs - `NormalizeTagArbTagValue` handled arbitrary input, including invalid UTF-8 and binary data, and consumed 4.5% of CPU in its processing service. - Production data showed: - Nearly all inputs were ASCII. - UTF-8 appeared in fewer than 3% of cases. - Invalid UTF-8 represented less than 0.01% of inputs. - A fast path optimized for common ASCII data made the function more than 90% faster without reducing correctness or safety. - The change generated projected annual savings of hundreds of thousands of dollars. - The result demonstrated that observability is essential: optimization decisions should reflect actual workloads rather than hypothetical edge cases. ## From Manual Optimization to Automation - Deep performance tuning requires specialized knowledge of profiling, compiler behavior, assembly, and workload analysis. - Although the results can be valuable, the process is time-consuming and difficult to scale across a large organization. - Datadog wanted to move beyond isolated “heroic” optimizations toward a repeatable and automated process. - The manual techniques used by performance engineers became the foundation for heuristics in BitsEvolve, an internal agentic system intended to optimize code systematically. Datadog’s experience suggests that organizations should combine production observability with compiler-level analysis, prioritize high-impact hot paths, and automate proven optimization patterns so performance gains do not depend solely on a small group of experts.

The Current State of LY Corporation (opens in new tab)

Tech-Verse 2025 showcased LY Corporation’s strategic shift toward an AI-integrated ecosystem following the merger of LINE and Yahoo Japan. The event focused on the practical hurdles of deploying generative AI, concluding that the transition from experimental models to production-ready services requires sophisticated evaluation frameworks and deep contextual integration into developer workflows. ## AI-Driven Engineering with Ark Developer LY Corporation’s internal "Ark Developer" solution demonstrates how AI can be embedded directly into the software development life cycle. * The system utilizes a Retrieval-Augmented Generation (RAG) based code assistant to handle tasks such as code completion, security reviews, and automated test generation. * Rather than treating codebases as simple text documents, the tool performs graph analysis on directory structures to maintain structural context during code synthesis. * Real-world application includes a seamless integration with GitHub for automated Pull Request (PR) creation, with internal users reporting higher satisfaction compared to off-the-shelf tools like GitHub Copilot. ## Quantifying Quality in Generative AI A significant portion of the technical discussion centered on moving away from subjective "vibes-based" assessments toward rigorous, multi-faceted evaluation of AI outputs. * To measure the quality of generated images, developers utilized traditional metrics like Fréchet Inception Distance (FID) and Inception Score (IS) alongside LAION’s Aesthetic Score. * Advanced evaluation techniques were introduced, including CLIP-IQA, Q-Align, and Visual Question Answering (VQA) based on video-language models to analyze image accuracy. * Technical challenges in image translation and inpainting were highlighted, specifically the difficulty of restoring layout and text structures naturally after optical character recognition (OCR) and translation. ## Global Technical Exchange and Implementation The conference served as a collaborative hub for engineers across Japan, Taiwan, and Korea to discuss the implementation of emerging standards like the Model Context Protocol (MCP). * Sessions emphasized the "how-to" of overcoming deployment hurdles rather than just following technical trends. * Poster sessions (Product Street) and interactive Q&A segments allowed developers to share localized insights on LLM agent performance and agentic workflows. * The recurring theme across diverse teams was that the "evaluation and verification" stage is now the primary driver of quality in generative AI services. For organizations looking to scale AI, the key recommendation is to move beyond simple implementation and invest in "evaluation-driven development." By building internal tools that leverage graph-based context and quantitative metrics like Aesthetic Scores and VQA, teams can ensure that generative outputs meet professional service standards.
