Route named `home` is substantially slower in both SvelteKit, Astro, and possibly other frameworks (in dev mode)

[dihmeetree]

Describe the bug

For some reason, if you create a route named home, it will take much longer to load than any other route (For example /test and containing the same content). This has been reproduced with both SvelteKit and Astro frameworks) in dev mode.

Note: This issue does not exist in production/preview (built/compiled) sites.

I've created an issue thread in the SvtelteKit repo for this issue https://github.com/sveltejs/kit/issues/12061#issuecomment-2067835993. I figured this was a SvelteKit issue at first, but it looks like this may be related to Vite (as user amit13k points out in the comment above)

If you're apart of the SvelteKit Discord, you can see our conversation here regarding the bug: https://discord.com/channels/457912077277855764/1223280626724241439

This issue seems to definitely affect Mac users. I've had 1 user say that they weren't affected on Linux, however another has said that they had the issue on Windows.

Reproduction

You can use my repo below, or just use the quickstart commands to create a project for both SvelteKit and Astro (included below) https://github.com/dihmeetree/svelte-bug-repro

Steps to reproduce

You can create a SvelteKit project quickly via the following command

npm create svelte@latest my-app

In SvelteKit create a route (folder) named home, and create a +page.svelte file inside it. Put some html in it and then load the /home route in your browser. Create a /test folder as well. The /home route will load much slower than the /test route.

And for Astro

npm create astro@latest

In Astro create a home.astro file in the pages directory. It will be much slower than your index.astro file.

I've tested with npm, yarn, and bun to make sure it wasn't an issue with a package manager as well.

I haven't looked into the issue much yet, but if accessing /home once is really slow, we might need to skip it on MacOS. Otherwise if it's only slow in repeated access, we might need to check if it's a caching issue so we only do it once.

Any updates on this? 👀

@dihmeetree I just noticed the same issue! Spent an hour trying to figure out why my Astro site was super fast except for the /home route. Renamed it to /home2 for testing, and it went back to normal Astro fast interactivity. Finally updated the site to point to / for the homepage.

My app details:

• Framework: Astro 4.12.2
• Render Strategy: SSR (output: "server")
• View Transitions: enabled (Default animations)

Yeah hoping this will be fixed! 😄 Definitely an annoyance... haha. Thanks for sharing your app details!
