it's unironically just react lmao, virtually every popular react app has an insane number of accidental rerenders triggered by virtually everything, causing it to lag a lot

well that's any framework with vdom, the GC of web frameworks, so I'd imagine it's also a problem with vue etc.. I don't understand though why performance (I.e. using it properly) is not a consideration with these companies that are valued above $100 billion like, do these poor pitiful big tech companies only have the resources to do so when they hit the 2 trillion mark or something?

Vue uses signals for reactivity now and has for years. Alien signals was discovered by a Vue contributor. Vue 3.6 (now in alpha/beta?) will ship a version that is essentially a Vue flavored Svelte with extreme fine grained reactivity based on a custom compiler step.

One of the reasons Vue has such a loyal community is because the framework continues to improve performance without forcing you to adopt new syntax every 18 months because the framework authors got bored.

The behaviour is a bit weird - I just opened mine and in Chrome task manager it showed the ram use climbing to 2.8GB, but in the network console it only shows a few 10s of mb download. I wonder what the discrepancy is? The site seemed to notice the console was open and behaved differently also.

Very few people with LinkedIn profiles read the social feed. Even fewer post things to it. The majority use LinkedIn only for job searching and keeping contacts. I do some times wonder if any hiring managers see a lot of LinkedIn social post activity as a positive thing. The few times we’ve interviewed candidates who had a lot of LinkedIn posting activity it was considered a risk: We could go through their LinkedIn a…

> Very few people with LinkedIn profiles read the social feed. Even fewer post things to it. Yes, but many of the people who matter in professional domains do. Much like all social media, the prolific few who do post have outsized influence, and engaging with them can often be to your benefit.

How? Legitimate question.

We now have simple chat apps capable of doing almost anything LinkedIn does while using under 100 MB of RAM.

A probe collecting data in space takes <70 kB of memory. I fail to see how this statement should make me feel happy

Space is mostly empty there is not much interesting stuff to collect and who’s going to buy that data

LinkedIn on the other hand has user behavior, computer details etc. that’s a lot of interesting data.

Fools, they lost a source of very valuable training data.

Nope. Google+ was a ghost town. They made the right call to shut it down and focus their efforts on YouTube. The videos and comments on YT are superb training data, every bit as good as Google+ was. In 2025, YouTube’s total revenue (advertising + subscriptions like YouTube Premium and TV) surpassed $60 billion. If they spun out YT it would have a market cap $500-600bn putting it in the top 20 companies. Google+ would…

Ghost town was the best part, for users like me. I didn't want another fb or insta. The circles and community were great.

I think that’s normal, I would expect RAM use to dwarf network transfer on most modern JS-heavy sites.

If a page downloads 1MB JSON, that could easily take 10MB (maybe much more?) RAM when parsed into an object. And JS code itself probably has a similar increase in size just by getting parsed into an AST. And all that is before really executing anything - once the dozens of shitty third party scripts start whirring, they will generate tons of uncollectible garbage because they are written by miserable people who don’t give a shit, understandably. And I bet LinkedIn has a hell of a lot of junk third party scripts injected by random spies I working in various corporate departments who need to spy on users to collect data to persuade their boss to let them do some dumb project to prove they deserve their job.

Tabs also render a bunch of compositor layers as bitmaps stored in VRAM, or just RAM, for smooth scrolling. Oh and there’s the DOM, I bet that adds up. I’m probably only scratching the surface. There’s so much going on in a browser tab. The front end is a marvel of engineering. Sites like LinkedIn of course exploit this for banal evil, sadly.

I don't understand who uses that network anymore. Everytime I login it's all ai generated stories next to ai generated flavor images of people sounding like a parody of themselves ("what taking my kids to school taught me about business scaling"). Out of all places to doomscroll, why choose the one that feels like an episode of Severance?

Anecdotally, I've noticed a correlation between spikes in LinkedIn social activity and subsequent job changes, after which the activity (typically) subsides again. The activity doesn't even have to be actively posting, just reacting to posts on their feed.

I think the dynamic you're observing is partly people just reacting to stuff (or if posting actively, fluffing up their "professional presence") as they do a job hunt.
