At Amazon every 100ms latency cost 1% of sales. Here's what we did

Is there supposed to be an answer to this or am I struggling with the UI? Here's how this looks to me. https://ibb.co/BTf9N1N https://ibb.co/BTf9N1N

  Same. I’m on mobile browser and not logged in. I don’t use Twitter and rarely read anything on it so I’m just assuming Twitter doesn’t care about mobile browsing non logged in people?

  I think it's a link to a retweet. Though whatever is making twitter act dumb, use this and it should work: https://twitter.com/amilajack/status/1484970823005868033 https://twitter.com/amilajack/status/1484970823005868033

No way. Since the start of the pandemic I was ordering groceries from Amazon Fresh. Adding/removing an item to/from cart takes couple seconds at very least. Expanding “similar items” can take up to ten seconds easily. It seems at times like they are using a blockchain or maybe a real human writes down my order on a piece of paper (and sometimes they have to run for a new pen). This is not a one-time experience or a rush hour. It always works like this, it’s just how it is built.

  Amazon Fresh runs on a different part of the infrastructure than Amazon itself. Your experience with Amazon Fresh does not correlate to the main Amazon front end. Disclaimer: I work at AWS, but not in any department directly related to the Amazon website itself or Amazon Fresh. However, I have learned some things about how they build their systems behind the scenes.

>Server side render everything >http://amazon.com http://amazon.com is server side rendered and has no client side rendering framework. The potential latency hit didn't justify it. >We were stuck with jQuery 1.6.4 Grimacing face >SSR React wasn't fast enough for us. This blew my mind. While SSR has gotten some more support in the past 1-2 years, This is not going to sit well with majority of HN crowds. One thing I really want to see is some sort of predictable latency rendering. Every page should render at fixed predetermined timing regardless latency ( Subject to Network latency difference so everyone would have different value ) . I dont like webpage that some times load so fast it felt it is punching me to the face while some links of it takes 3s to load.

  Sits well fine with me. Client side rendering is bad for users and bad for Search Engines...

And yet pulling up recent orders takes a decent amount of time, individual items take a lot longer, and don't get me started on 2 day shipping taking 3-5 days after it "ships" the vast majority of this spent in Amazon logistics before hitting USPS / UPS

  I’m sure they know. They have a boatload of customer-oriented metrics that they track on a daily basis. And I’m sure there are multiple simultaneous projects going on to address various parts of that delay. But you and I are just two customers out of the hundreds of millions that I presume they serve on a daily basis, and they can only work on their average, median, P90, P99, and P99.99 results.
