Wrote a blog post on "Understanding Long Tasks data in Real User Monitoring" Hope it opens up new opportunities in web performance monitoring.

Elastic Ramen ( CLI harness for SRE investigation and remediation) bridges that gap. Same conversation, same Elastic context layer, now in the terminal where the fix actually lives.

Observability tools tell you what went wrong. They rarely help you fix it.

During an incident, Engineers bounce between Kibana, Slack, and the terminal/IDE often. Every tool switch, the assistant stays behind in the previous surface, and the investigation restarts from scratch🧵

@threepointone Lovely framing and great read, immediate thought comes to mind is what would happen if we feed this post to the coding agent 🤔

🔥 The newest web compression API announced by @patmeenan at #PerfNow

It could be up to 95% more efficient than existing gzip/brotli methods. All leading browsers agree on the spec => it will be shipped soon, and it's super exciting.

This launch is super close to me personally as it allows the developers to measure the Web performance aspect while ensuring the website is functional. Ex: Super handy during functionality/load tests on peak season (black friday).

What I have been working on lately - Elastic Synthetics monitoring.

You can write End-to-end synthetic suites in JS and run them on multiple pop's to understand the website performance. #synthetics #webperf #playwright

@PKodmad Congrats to you and your family, Truly amazing times.

[Vignesh Shanmugam @_vigneshh]

Agree 💯, Copilot helps with rapid prototyping when your mind is empty and you are staring at your IDE. But damm the effort you put in to debugging because of the buggy code it produces 😅

Check out the blogpost we wrote on this architecture around 2016

Year 2015 coming back to my memories reading this blogpost - https://t.co/nDPwhAf06X

We were running similar architecture for almost 3-4 years at @ZalandoTech - https://t.co/D2goe5hA2T with lots of other goodies like caching, Observability, backoffs, pooling etc.

@_prateekbh Come to Seattle bro!

[Vignesh Shanmugam @_vigneshh]

@siddharthkp @_prateekbh @ankeetmaini Only thing that helped while I worked at Zalando in the past
1. Tooling to figure out how the components are used by different teams - https://t.co/p4xsR2zziT

2. Planned updates - Each team has a dedicated owner who sort of helped to migrate.

We’ve built some unusual new features for Elastic Synthetics 8.4.0, now we’re finally talking about them: https://t.co/pUltN6fWOT . Watch me and @justin_kambic discuss

@Zizzamia @coinbase Gotcha, makes total sense on the long tasks part.

Does the 2second dynamically get adjusted if one of the JS resources takes a long time to load? Otherwise a page could cheat and delay the render and nothing gets measured. Do you tackle this case?

[Vignesh Shanmugam @_vigneshh]

@Zizzamia @coinbase Basically how you decided on the 2second mark for calculating the NTBT.

@GergelyOrosz Ex Zalando engineer here. Zalando used to pay 150EUR/day back in 2017-2018 and it's per week (1050 EUR).

[Vignesh Shanmugam @_vigneshh]

@_prateekbh @VivekNayyar09 Big in the UI itself on how it's calculating percentiles.
