Thank you for asking! Yes, I do still have some performance issues with the forum. Seems like first load with a cold browser cache is the main or only issue. After the initial load the forum behaves more like a single page application (only partially loading pages) and is generally fast. The Firefox developer tools indicates a download of something or other is hanging and blocking progress towards a usable, interactive page. Sometimes it takes more than a minute before I can do anything (I’ll call that my “minutes-long issue” below).

Firefox asset download details: OpenSans-Regular.ttf is blocked but requests for /fonts/OpenSans-Regular.ttf?v=0.0.9 succeed (HTTP 200).
Ah, OpenSans-Regular.ttf is blocked by Firefox because it is hosted on a different domain. Maybe that is blocking other assets from loading as well? Check out these errors from the Firefox console:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://nextcloud.com/wp-content/themes/nextcloud-theme/dist/fonts/OpenSansRegular.ttf. (Reason: CORS request did not succeed). Status code: (null).
downloadable font: download failed (font-family: "Open Sans" style:normal weight:400 stretch:100 src index:2): bad URI or cross-site access not allowed source: https://nextcloud.com/wp-content/themes/nextcloud-theme/dist/fonts/OpenSansRegular.ttf
I can reproduce this CORS failure in the Chromium browser.
https://www.webpagetest.org/result/220911_BiDcQK_879/ shows a timing of <5sec for an interactive page, so doesn’t really count as a good independent repro outside my home network of the minutes-long issue, but it does show several blocking assets and a 4xx HTTP error response code for OpenSansRegular.ttf.
https://www.webpagetest.org/result/220911_BiDcQK_879/3/experiments/ has some really interesting suggestions, including a couple related to the OpenSansRegular.ttf issue above.

Resume: pmtu 1492 hops 10 back 10
mtr -n help.nextcloud.com tries harder, and it shows that “no reply” hop is from a router with IPv4 address 4.68.38.173. It shows 90% packet loss from that router. I’m guessing that router is in Finland based on the similarity of the IP address of the next router. Here’s a snapshot of mtr output:

Browser details: currently I’m running Firefox 64-bit v104.0 (just whatever is the latest available in the deb/snap repositories for Ubuntu 20.04 and 22.04 LTS) on an Ubuntu desktop or laptop. I can repeat my minutes-long issue in the Chromium browser.
Network details: I’m paying my ISP for 1gbps up and down. Latency is generally very good: 2ms average pings to google dot com. Low jitter with these pings, too. I use a Pi-hole, and I notice it blocks stats.nextcloud.com, so piwik.js is not downloaded by my browser. This doesn’t seem to cause any issues.
