@ChrisKitching17, our CTO and co-founder of Spectral Compute, recently presented at the 𝗡𝗛𝗥 𝗣𝗲𝗿𝗳𝗟𝗮𝗯 𝗦𝗲𝗺𝗶𝗻𝗮𝗿 hosted by NHR@FAU. The recording is now online: youtu.be/uSLD40GX5nM

This core philosophy drives our upcoming talk at the NHR PerfLab Seminar hosted by the Erlangen National High Performance Computing Center (NHR@FAU), where Spectral Compute's Founder and CTO, @ChrisKitching17, will be taking the virtual stage on Tuesday, April 28th.

Sparse tensors galore! #NHR PerfLab Seminar today at 2:00 p.m. CET: Jee Choi from U Oregon talks about "Learning Efficient Sparse Encoding for High-Performance Tensor Computations." Details and Zoom link: hpc.fau.de/2026/02/26/nhr-pe…

I’m super hyped and happy to announce that I’m getting even deeper into helping agents reason about software quality as I join @getqatech! Since I’ve started working on PerfLab and then PerfAgent this has become an obsession. Now I get to do that full-time and I could not be more thrilled to find such a great alignment. Expect more awesome stuff soon on agents, web performance and software quality!

Don't miss the online talk by @mattgodbolt on "Exploring Compilers for #HPC" in the #NHR PerfLab Seminar tomorrow, Sep 2, 2:00 p.m. CEST. Details and Zoom link: hpc.fau.de/2025/08/26/nhr-pe…

Oh great. I’ll take a look. Yesterday I had a meeting where the founder asked about getting more performance info on frontend. I handle backend but I told the frontend dev to enable sentry tracing. If we start actually using Perflab I’ll let you know.

It's time for something Neuve neuve: [adj] new (brand new) It's time to share a concept that I'm beginning to obsess about and am keen on pursuing. It's about the future experiences and web browsing. TLDR: Read the Neuve Browser Manifesto here: notion.so/Neuve-Browser-Mani… After spending the last year and a half building PerfLab, and the last 3 months building PerfAgent. I became more ingrained into browsers and how they work. After an introductory chat with @seb_thunman, I was struck by this concept. It felt like such a natural evolution of what I was building and how much into browsers I'm getting. After seeing @liadyosef and @kentcdodds threads on how future interactions can be shaped and how much simpler and yet powerful interfaces and experiences on the web can be. The basics for the concept: A generative, agentic web broswer. Think of V0 MCP Agentic Browser AI dev tools = Personal web achieved. Bringing forward a new way to build, interact with and even think about the web. Seeing how for ever change are our concepts of what anyone can build, imagine, achieve are. How much more personal tools such as @v0 make the web be. Read the full manifesto here: notion.so/Neuve-Browser-Mani… For anyone reading this, a quick introduction about my journey so far. A bit more than a year ago I decided to create my own performance devtool, perflab.io. I've forked @ChromeDevTools and built on top of it a standalone application that create easy to read insights from traces. The timming was perfect, as the Chrome team would announce the future plans for the Performance panel in 2024. After building it I've seen that I ended up building another dashboarding tool, now with more text. So I've started building agent.perflab.io. Rethinking the concept with two goals in mind: remove friction and lower the barrier to entry. Basically building the smallest subset of initial UI for a devtool, removing any restrictions and yet keeping insights and information accessible. Now with the experiences gathered I cannot help but think how web experiences are bound to change. It's time to experiment, and shape a new web.

Among this year’s participants: @matteocollina, Node.js TSC member @mgechev, Angular Product Lead @ Google @xenovacom, Transformers.js creator @ThisIsJoFrank, Deno team @zkochan, pnpm maintainer @crowlKats, working on JSR, Deno team @satanacchio, Node.js TSC member @PaoloRicciuti, Svelte contributor @devdevcharlie, Practical ML in JS with TensorFlow.js author Moderators: @HowDevelop, OSS Enthusiast, & @WebTwitr, PerfLab Founder

Now into the final adjustments, highlighting the different sections of time and its animation frames as you click on the different buckets. This will be an interesting experiment to release into PerfLab 😁

Just as I prepare for my trip tomorrow to #perfnow I finally pushed a small but meaningful update to PerfLab to how the INP event is displayed on the timeline when you highlight it on the trace viewer. More in line with the INP insights overlay native from DevTools 😁

Working on a better breakdown for AnimationFrames on trace entries for PerfLab. There are, for now, some reasons why an animation frame might have gaps in the attribution and those are well documented @nomsternom and @tunetheweb article: developer.chrome.com/docs/we….

After pulling the latest patches from DevTools into PerfLab I've noticed the new Layout Shifts track and oh boy the DevTools team is on fire! It's already enabled on perflab.io but you can enable it with the Layout Shift track experiment (second image)

Today at 2:00 pm: Estela Suarez from #SiPearl speaks about "Co-designing a European #CPU for HPC and Ai" in the #NHR PerfLab Seminar hpc.fau.de/2024/10/22/nhr-pe…

Learning how to reason and utilize raw trace data is quite powerful. Learning how to do that within DevTools source code for PerfLab is quite an unique experience.

Here's an update on what I've been working on PerfLab! On this update: - Fullscreen trace viewer now shows the trace reports. - Third Party data and trace highlighting - LCP resource loading highlighting on network track Watch the video or follow the 🧵 youtu.be/apoqoffwmeE

Featured posts this week: ⚡ Introducing Speed Brain: @ackriv @SulemanAhmadd @Cloudflare ⚡ PerfLab tool: @WebTwitr ⚡ The curious case of Marriott: @BeaderHoward @Catchpoint ⚡ The Power of Web Performance: Daniele Merola Special thanks to the authors.🙏

Another exciting new possiblity that I quite believe will forever change how teams work with profiling sessions is the hability to add annotations to trace files! This will soon be made available on the default DevTools experience as well, but it is already available at PerfLab

Alright, the time to get more eyes on this has finaly come! I'm super excited to share more about PerfLab! A project of mine that I've been working this year. A tool to help devs with perf problems, and is now ready for its 'alpha' debut! Story time...so here comes a 🧵
