We've got 2 brilliant lectures on real production case studies on reducing memory footprint by order of magnitudes. One from DoubleVerify, using hackie but efficient data structures, and the other from Next Insurance with 4 real world methodologies shown on stage. Thanks to **DoubleVerify** for sponsoring and hosting the event! **AGENDA** 18:00–18:30 **Mingling, food, and drinks** 18:30–18:40 **Opening words** 18:40–19:25 **Beautiful Code Is Overrated: How "Ugly" Engineering Saved Geo at Scale / Alex Cherny - DoubleVerify** 19:30–20:15 **Bulletproof Cookbook to Reduce Your Service's Memory** **/ Haim Yadid - Next Insurance** **Beautiful Code Is Overrated: How "Ugly" Engineering Saved Geo at Scale** We often celebrate clean, elegant architecture, but when data grows 30× overnight, beauty doesn't keep the lights on. This talk walks through a real-world case study of how the Geo traffic service at DoubleVerify broke under 500M IP ranges and how a brutal, byte-level approach outperformed every elegant solution. I'll share the challenges, trade-offs, and the unconventional design choices that helped us slash ramp-up time from 70 minutes to under 3 and memory from 193GB to 13GB. Sometimes, "ugly" is what scales. **Alex Cherny / DoubleVerify** Alex Cherny is a Director of Software Engineering at DoubleVerify, where he leads large-scale Traffic systems operating at millions of requests per second. He has extensive experience building and optimizing JVM-based distributed systems under strict latency, memory, and reliability constraints. Alex focuses on pragmatic performance engineering and believes that clean abstractions are valuable—until scale forces you to break them. **Bulletproof Cookbook to Reduce Your Service's Memory** In recent months, I’ve been working on a Java service that constructs and processes large in-memory object graphs. The memory consumption has become substantial. As a result, through a systematic analysis and targeted optimizations, I have managed to cut the memory footprint by more than 60%. Leading to cost reduction. In this session, I’ll guide you through the journey - from identifying the memory issues using Eclipse MAT to implementing practical optimizations that led to these savings. You’ll learn how to apply similar techniques to your own services to reduce resource usage and improve performance. At the end of the talk, I will also mention several optimizations that improved runtime performance by a factor of 4. **Haim Yadid / Next Insurance** A software engineer with over 30 years of experience in various technology fields: software development, team management, software architecture, HPC and algorithmic research. In my day job I work in Next Insurance as an engineering fellow where I am involved in numerous cross R&D strategic projects. Before that has been focusing for 8 years on Java platform performance optimization as an independent consultant and was involved in more than a dozen optimization projects. I am a Java Champion and one of the founders of Java.IL, the Israeli Java user group. **FOOD** Light food, light drinks, and beer will be served courtesy of **DoubleVerify**. **RECORDING** We are recording, as always, this meetup and uploading it to our YouTube channel (be sure to subscribe), but please keep in mind asking questions about stuff you don't understand is only possible when you attend the live event. **ADDRESS** Alon Tower 2, Yigal Alon 94, Tel Aviv Floor 27

But in Node.js, these tools are not free, and used without care they can become a serious performance bottleneck. In this talk, I’ll share real-world lessons from production Node.js systems where adding observability actually degraded performance. We’ll look at the hidden costs of logging, async logging, AsyncLocalStorage, distributed tracing, and high-cardinality metrics — and why these issues often only appear under real load. ​ ​-------------- Kindly be informed that attendance at the meetup is on a first-come, first-served basis until capacity is reached.

**Join Us for the next Israel LLVM Meetup!** We’re thrilled to invite you to an exciting evening, where we’ll dive deep into cutting-edge compiler technologies and hardware-aware optimizations. This meetup brings together the LLVM community for insightful talks, networking, and discussions on the future of compiler infrastructure. Expect a diverse lineup of sessions covering Triton, MLIR, and LLVM optimizations powered by hardware metrics — perfect for compiler developers, performance engineers, and anyone passionate about high-performance computing. 📅 **Date & Time** **February 18th, 2026** • **17:00** – Arrival & Networking • **17:30** – Talks Begin • **19:00** – Wrap-up 📍 **Venue** [Jem’s Hertzliya](https://share.google/5taousLhsVfY7ox0r) 🎤 **Speakers & Topics** **• Jonathan Cohen - Compiler Engineering Manager - Apple** Title: “Supercharging Compiler Optimization Remarks with Hardware Metrics” Abstract: This session demonstrates how to turn hardware counters with compiler optimization remarks into performance wins. It combines performance analysis metrics with enriched Optimization Remarks to debug and mitigate performance bottlenecks - a challenging task for compiler developers or performance engineers. **• Michael Zuckerman - AI SW Engineering Manager – Majestic Labs AI** Title: “Triton for RISC-V: Bridging PyTorch to RISCV with MLIR & LLVM” Abstract: Triton is a powerful open-source programming model originally developed to generate highly optimized GPU kernels for deep learning workloads. In this talk, I present an extension of Triton to target the RISC-V vector architecture, using MLIR and the LLVM toolchain as the compilation backbone. This work creates a practical bridge between modern PyTorch-based machine learning frameworks and emerging RISC-V hardware platforms, enabling efficient and portable execution of AI workloads beyond traditional GPUs. The proposed integration allows PyTorch models to be lowered end-to-end into RISC-V vector instructions, leveraging open compiler infrastructure to significantly reduce the effort required to enable new hardware targets. I will show how Triton kernels, TorchDynamo graph capture, TorchInductor scheduling, and MLIR/LLVM code generation were aligned into a unified backend that supports rapid bring-up, iterative optimization, and transparent performance tuning. This talk demonstrates how an open, modular compiler stack can accelerate the adoption of flexible hardware architectures in machine learning, while preserving high performance and developer productivity.

**Abstract:** The Advanced Photon Source (APS) is an X-ray light source at Argonne National Laboratory where researchers perform imaging, diffraction and spectroscopy experiments at 68 specialized beamlines. APS recently completed a major upgrade that made it the brightest synchrotron in the world and upgraded many of the beamlines to take advantage of the dramatically brighter, more coherent beam. These new capabilities are increasing the facility’s raw data production from <10 PB/year before the upgrade to >100 PB/year once all instruments are back online. To meet this data challenge, the APS Beamline Data Pipeline project team is partnering with beamline staff to develop and deploy science data pipelines that use a common set of open-source software tools (many written in Python) to link instruments with the Polaris supercomputer at the Argonne Leadership Computing Facility (ALCF) for data processing. This talk will describe the APS data systems, our file-based and streaming pipeline templates, and some of the open-source software we use to extract scientific insights from beamline data. **Audience Takeaway:** Open source Python data acquisition and analysis tools are ubiquitous at the APS. Many of the packages that are mentioned can be found at [https://github.com/AdvancedPhotonSource](https://github.com/AdvancedPhotonSource). This is a *hybrid* event. To attend online, join us on Zoom here at 6pm: [https://numfocus-org.zoom.us/j/89399976851?pwd=UEgMUZXdYmKdK1x1dIPL6hwUYnp7NW.1](https://numfocus-org.zoom.us/j/89399976851?pwd=UEgMUZXdYmKdK1x1dIPL6hwUYnp7NW.1) **Sponsor**: Grainger will provide the meeting site, as well as snacks for the onsite participants. * **Address:** 222 W Merchandise Mart Plaza, 18th Floor, Chicago, IL 60654 * **Grainger's Overview:** W.W.
