See also: Help.nextcloud.com slow page load times
I’m also seeing consistently slow (first view/cold cache) page load times for help.nextcloud.com. Over a minute to be able to see and do anything. Similar results in both Firefox and Chromium.
I’m really confused why I can’t reproduce the problem using www.webpagetest.org. Timings from that site are consistently and reasonably fast enough, say, 5 seconds or less. So I’m trying to isolate what might be different between www.webpagetest.org and my home network. One difference is DNS.
I thought perhaps when stats.nextcloud.com is blocked it slows down the help.nextcloud.com user experience. At home I am usually blocking stats.nextcloud.com using a Pi-hole. This uses a DNS trick so stats.nextcloud.com resolves to 0.0.0.0. With the DNS block in place, it takes minutes for the first/cold page load of https://help.nextcloud.com. But when I allow proper DNS resolution for the stats.nextcloud.com domain it seems to take just as long.
It works quickly on my mobile phone web browser when I am not on my home network (and not behind my Pi-hole), though.
I think we really need help working through a browser-side performance profile showing each URL, which ones take a long time, and especially looking for anything that blocks. Anyone have experience doing this? I can definitely see some scripts taking a long time when I’m using Firefox Developer Tools but I’m having trouble sharing the result.
I also tried the curl timing examples others mentioned (very cool, thank you!) but the results are intermittent. One time an avatar placeholder image will take 2 minutes to fetch, then another time it’ll take 2 seconds.
