Devs should really grab an old netbook from ebay with an atom cpu and 1-2GB of ram and see how well their new React app works on that
@mikoto I bought a 2GB RAM/16GB SSD Intel Atom mini-PC long ago, back when Windows 10 was new. It swapped constantly and was unusable for _any_ purpose. I tried switching it to ChromeOS and it was slightly better, but still barely usable. 2GB is just not a realistic config anymore.
@stilescrisis browser devs also need to optimize too

How an Atom PC can run XP with Office 2003 (or even Debian with Libreoffice) fine but not a modern OS is really more of a sign how bloated everything has gotten more than anything.
@mikoto Browsers are faster now than they were in XP times, by any metric you choose.
@stilescrisis @mikoto It's hard to compare because sites aren't the same but I think your claim is not clearly true. Nobody cares that the jit is 5x faster now or that it even exists. The browser ui layer is much slower and more bloated, and more interactions have delays waiting for network or js code to do things rather than just doing it, and memory efficiency is much worse (= cache misses and swapping).
