I built an Electron app Video Hub App and it's fast:

Electron is overkill for a todo app that you want users to open/close many times per day. But if it's an app that's used for 90% while it's open and is used a few times per week, who cares if it takes 2 seconds to start?

I don't understand what everyone is moaning about with Electron. My app uses 130mb of RAM -- is that too much to ask for, for a dedicated video browser?

ps - here's also a file renamer I built with Electron: https://github.com/whyboris/Simplest-File-Renamer

In my experience, my VSCode setup responds just as fast as my fully extended VIM does.

Are you remoting into your vim on a satellite link or some really far away box somewhere?

I see no other rational explanation here

Somethings wrong with your vim setup then.

I barely have released the return key after typing mvim and the macvim window is already there. Even Sublime is not that fast.

Aside from the initial load that all Electron apps suffer from, Insomnia feels pretty snappy to me. Granted, I only have a few dozens of API that load 20KB of JSON max.

I love Insomnia and usually recommend it to others.

But I remember a few months ago I was developing a basic API and testing it through Insomnia. At first, I almost had a heart attack seeing the time it took to answer, between clicking "send" and getting a response back. All this running on localhost, on an old but fairly powerful box (i7-3930k, 64 GB ram). My first reaction was I must have had some sleep() lying around.

Then I looked at the details, and the actual time taken handling the call, etc, as reported by Insomnia was a few ms, all the rest was... I don't know what.

But I do agree than other than that, when interacting with the app itself (switch requests, type, etc) it feels snappy enough. I usually use it alongside IntelliJ, which while fairly fast, isn't terminal-level instantaneous.
