Initial Server Response Time (Nuxt 3 SSR)

Support
, ,
1

PLEASE help us help you by writing a good post!

We switched to a PRO Account on Netlify, but what we still stumble across is the initial server response time which seems pretty slow and disturbing.

Site: https://frolicking-clafoutis-07566a.netlify.app or https://www.regiolix-solutions.at/

I’ve run both domains through testmysite.io (Website Speed Test Tool - Testmysite.io by Netlify) where the result confirms lighthouse and my “personal eye”.

There seems not build problems except a few warning from netlify functions. Maybe there’s a problem though?

==== edit

I read somewhere netlify is not using the EDGE Network by default. So added the following preset:

nitro: {
    preset: 'netlify-edge',
  },

Now I receive another error:

Hope you guys can help me :wink:

Thanks.

Just to clarify, based on the conversation that we had in the helpdesk, I thought you were trying to use Edge Functions because you know the regular functions will be slower. That’s what you even said:

Because the netlify-edge preset was the way I tried to reduce the initial server response time.

I read that response as, Netlify preset is working, but it’s slow and Edge Functions preset it not working - so to increase the speed, I want to use Edge Function preset. But then you clarified that you were asking only about the initial response time.

About that, unfortunately, this is almost expected behaviour. Unlike Edge Functions, Netlify Functions are locked to a single region - and are easily affected by cold-start issues. So, if your site doesn’t receive continuous traffic, a first visit after some time can take up to 2 seconds in some cases. However, any subsequent loads take as much as 500 ms - in my testing.

If you’re seeing times slower than that, feel free to share a HAR file recording.

Thanks for the response. As you suggested in the support I created an issue on GitHub. This one got fixed. Therefore I am now able to deploy on the Edge with NEtlify. Sadly Netlify throws an error in the logs when trying to access the corresponding site. (Already commented that on GitHub too, but maybe you can help though!)
