Windows 11 slow startup

DaWoodster · January 24, 2024, 1:28am

I know it’s been asked here before, but I haven’t seen a resolve. It takes 2 - 4 minutes for gsender to start. Works fine otherwise, and I’m a fan, without a doubt my goto gcode sender. So, I’ve been just dealing with this for quite some time, but I’d love to get a fix if there is one.

All my recent gSender versions have been really slow loading. There’s also no indication that it is loading either.

Apparently, unless 1.4 solves it, there’s still a long startup delay.

Hey @DaWoodster,

This isn’t a result of gSender, it’s your virus protection doing a scan when you first load up. You can test this by letting gSender load initially, then closing the program. When you load it a second time, it’s super quick as it doesn’t get scanned again.

Cheers,
Stephen

Then explain why this doesn’t happen with ANY other program started on the same computer?

Also, it can do it every time gSender is started.

Is there a way for us to see what is happening in real time? You obviously have some factual information behind your statement, so how about revealing how you came up with it?

Hey Tex,

It’s a longstanding issue with Electron on specifically Windows with Windows Defender but also occurs on other operating systems with scan + protect.

You can read a bit more about it on the Electron Github if you’re interested:

### Preflight Checklist - [X] I have read the [Contributing Guidelines](https:/…/github.com/electron/electron/blob/master/CONTRIBUTING.md) for this project. - [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/master/CODE_OF_CONDUCT.md) that this project adheres to. - [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a feature request that matches the one I want to file, without success. ### Electron Version 13.1.4 ### What operating system are you using? Windows ### Operating System Version Windows 10 Version 21H1 ### What arch are you using? x64 ### Last Known Working Electron version _No response_ ### Expected Behavior The first file, referenced by `index.html` (loaded by `main.js`) loads as fast as the files after the first file or at least much faster. ### Actual Behavior The `main.js` loads a file `index.html` that itself references a style sheet and a JavaScript file: ```js function createWindow() { _mainWindow = new electron.BrowserWindow() _mainWindow.loadFile(path.join(__dirname, "index.html")) _mainWindow.on("closed", () => _mainWindow = null) } ``` The style sheet that is referenced first takes around 1.7 seconds to load while following files take only like 1ms to load. The start up time of my Electron app is delayed by this 1.7s because of this. I don't know where this delay comes from and how to fix this in the user code. See the output of my test application: ``` $ npm start > electron-performance-issue@1.0.0 start D:\electron-performance-issue > electron . Loading: file:///D:/electron-performance-issue/app/index.html (14 ms since last load) Loading: file:///D:/electron-performance-issue/app/index.css (1775 ms since last load) Loading: file:///D:/electron-performance-issue/app/index.js (0 ms since last load) ``` I considered using Webpack but - The [electron-webpack-quick-start](https://github.com/electron-userland/electron-webpack-quick-start) uses old dependencies and I didn't manage it yet to get it running with current versions - I like to keep out this additional dependency and configuration effort ### Testcase Gist URL _No response_ ### Additional Information I made a repository with the minimal code for this issue: https://github.com/c3er/electron-performance-issue

So the “Why is it not other applications” reason is “most of your applications are not Electron on that computer”.

It’s obviously something we’re aware of but unless either a fix is pushed upstream or we swap off Electron to an alternative it’s something we’re stuck with for now. There are alternatives for at least Windows (disabling Smartscreen Defender) but I’ve personally not looked deeply into Mac solutions.

Thanks for responding. So, if I exclude gsender (whitelist it) in defender, will it resolve to load faster? BTW, I also have it installed on a Win10 PC, and although still slow, it’s still usually under a min, so considerably faster than the Win11 install.

I have wondered in the past if Electron was slowing gSender startup down but I dismissed the thought because I use VSCode and that starts almost instantly. Maybe because it’s Microsoft’s own software they made Defender not slow it down? I don’t know.

I’m purty sure that this conversation will continue in 1.4 because no solution has been provided. We’ll see.
