Hi, @Levous, the
x-nf-request-id in the file named
netlify-fast3G.har does show a response timing of only 191 ms from our system. This is a fairly slow response for such a small ressponse.
Part of that is due to this being a “cache miss”. The CDN node didn’t have this content cached and therefore required a load from the origin.
For cache hits the response times are mostly under 10 ms from the point of view of the CDN node.
Also, I see that the shared hosting request is inside the UK to a server in the UK. For the Netlify request is it from the UK to Germany.
Last but not least, there is a 0 ms DNS lookup for the shared hosting while the Netlify site lookup was 278 ms.
I don’t have specific advice for improving this. Loading the page several times to prime the CDN cache would provide better results. If you prime and then test this would show how the site performed once cached in the CDN nodes locally.
Also, investigating why the DNS lookup was so slow would be worth looking into as well. What DNS resolver are you using?
If there are other questions about this, please let us know.
