My experience too, and that's not even touching the disproportionately high RAM usage of frameworks like Electron. Sure, "unused RAM is wasted RAM", until the system starts swapping heavily because of the high RAM usage.
It doesn't even have to be old devices, there are still laptops being sold with 8GB of RAM in 2026.
Electron would be fine… if most of us were running just one electron app.
In reality we’re stuck with 2-5 electron/CEF apps plus whatever is running in browser tabs as well as whatever webviews system stuff are running, which all quickly pushes into VM paging territory on low memory devices.
This is so true. It even happens to me in my 16GB work laptop when I have to use multiple Electron apps at work. My personal 8GB Air is way faster.
On the other hand, WebViews can be really fast without the baggage of Electron and Javascript frameworks/libraries.
