What Hacker News says?
Why do you think that is a bad header compression scheme for a static protocol where the majority of traffic contains those headers/values repeated over and over? That indexed table shaves about 30% off header size. https://www.keycdn.com/blog/http2-hpack-compression

HN discussionYou could also set up a cookie-free domain and have your static assets accelerated by the CDN while keeping your files (which send cookies) on a separate domain. You can still use a CDN in this case however, by default files with cookies cannot be cached on a CDN's edge servers. Some CDNs have the ability to exclude the cookie from the static file such as KeyCDN which allows you to ignore the cookie and/or strip it…

HN discussionI believe it's still worth it. Using a CDN will definitely help speed up the delivery of your static assets especially to those who are further away from your origin server. They're also quite simple to set up as there are many Wordpress plugins out there that allow you to simply enter your CDN url which will rewrite your current static asset URLs (e.g. CDN Enabler). Using a pay-as-you-go CDN service would likely be…

HN discussionPHP 5.4..? I'd recommend setting up WP Super Cache (which you're using now) to serve static HTML files (not sure what caching method you are using). Then you need to configure Apache (or switch to nginx) to actually look for those files, otherwise the plugin won't do much (it generates PHP files by default which are taxing on the server). Another option would be to switch to the Cache Enabler plugin (along with Apac…

HN discussionHaving correct cache headers helps as well, as a single visitor probably comes back to the page fairly often, or visits another page with shared assets. It's surprising how often some things that should be cached come back with headers that make it uncacheable by the browser. KeyCDN has a pretty comprehensive guide: https://www.keycdn.com/blog/http-cache-headers

HN discussionIts a vue.js site that I host statically on Netlify, with django backend on heroku that pulls all the data. The trick to get things to load quickly is caching the data on https://www.keycdn.com/ (with the right headers you can set it up that the CDN queries the slow pages in the background and serves the cached ones meanwhile to keep things near real-time). I might do a writeup about that it took me a while to figur…

HN discussionTrue, but if you compare to AWS, the S3 "First 10 TB / Month" tier is $0.09 per GB [1], and the Cloudfront "First 10TB" north America tier is $0.085 per GB and more for other regions [2] - or if you look at KeyCDN [3] for America that's $0.04 per GB, and again more for other regions. So HillRat's $0.05/GB figure isn't the most expensive out there :) [1] https://aws.amazon.com/s3/pricing/ [2] https://aws.amazon.com/c…

HN discussionIt's a combination of different headers that's hard to sum up in a short comment.

HN discussionYes, but that is all the CSS you will ever need to have. If you assume an average of 2.3MB[0] on the common page, that is about 3% of your project size for CSS that will not grow past that (atomic approach implies that you won't change it as we add more styles to your page(s)).

HN discussionYour quip here ignores the original conversation, which is about "dev tools for designers." You also conflate the "bygone days" of slower connections with the "bygone days" of monolithic rich media binaries/downloads. Average web page size has increased dramatically over the last decade [1][2], suggesting "massive sites" are more of a today-problem than a bygone one. I understand "Flash" was the trigger-word here, a…
