Thanks for your patience on this! We looked at both sites- your DNS is set up correctly so then we looked in our logs at response times. TL;DR, we didn’t see anything unusual with your site or load times. With page speed tools like the one you used, we’d recommend testing twice from the same location, since the part of Netlify’s architecture that makes sites fast is that users load from our CDN nodes around the world… but the site has to be in the node cache first in order for it to load quickly for other visitors.
More details if you want them: our logs for https://pavsidhu.com show that the average response time over the last week was ~209ms, which we think is reasonable. The slowest, but still pretty fast, times for that site were ~1.5s and those requests were for assets that were not cached in our CDN nodes, so they had to make a round trip to our origin in SF from (mostly) Australia.
The story with https://traintomaintain.co.uk is a little more interesting. For most of the last week, response times have been ~870ms. We think this is a bit slower than your other site because it includes some large (> 2MB) images. There were a few outliers though that took more than 20s to load! These requests were concentrated in two “events” lasting less than an hour each and the user-agents were all mobile phones. We think those load times were due to loading big assets over mobile networks, which are less reliable.
Hope this helps! If you continue to see slow timing, please come back and let us know and we’ll see what we dig up.
