Ironically I have always found it seriuosly slow to point of mind-boggling that the slowest site I ever use is help.nextcloud.com. Not a mark of honor. Then yesterday it wasnāt loading at all. And so I tried a proxy, but not luck there either, so I tried Tor too and am on Tor now, the only way I can see or interact with this forum.
Lift thy game, Nextcloud! Lift thy game.
Can you share the location and the service provider? And the proxy, is this a public one and in which network?
With the TOR network, you know that you and Nextcloud have the bandwidth to have a better connection.
Iām in Hobart, Tasmania. Service provider is TPG (Retail) and NBN (provider), and the proxy was ProxySite.
Hardly relevant though because: from this site I surf the internet, use all its diverse services and server websites and webservices from it all day every day, with top performance, streaming movies as desired, and never have any performance concerns. Until I hit help.nextcloud.com. Then itās over, red rover.
Seattle, WA (USA) user here with fiber gigabit via CenturyLink. No VPN, proxy or whatnot. No issues with any other site, just this one.
Initial loading of any forum page takes 4+ minutes regardless of browser, OS or device. After logging in and refreshing a page I already visited it takes about 10-20 seconds.

Like @mackov83 I also get lots of blocked CORS requests.
To give perspective, the WaniKani discourse, a Japanese language learning community, takes about 2 seconds to load on a fresh laptop that has never visited the site before.
Unfortunately, itās not that obvious. How do you explain that it works better with TOR network.
I have no idea what is wrong, but peering can be a factor that is hard to analyze (https://www.hetzner.com/presse-berichte/2015/01/156830) and if itās not filled up links, there can still be configuration problems in some networks, firewall settings etc.
This is the reason we ask for the destinations and operators, if we can find some pattern for users with slow connection.
I came across here from this conversationā¦
https://help.nextcloud.com/t/help-nextcloud-com-is-very-slow/133237/17
Like others Iām also having issues with the forum and have had for a very long time. I started using NextCloud on a personal server in the beginning of 2020. I rarely use this forum because of load time issues. It would be a godsend if the issues could be resolved. The load times seem to be better than I first tried using it. It may be only the first page load that is extremely slow after that it seems to speed up. Perhaps something to do with setting up cookies or session configuration. I really have no idea.
Firstly lots of Kudos for the team at NextCloud. This is a valuable piece of software for backing up my personal data. Although I am considering moving to an online paid service because of security concerns of configuring my own server.

I note the different path it is taking in this tracert.
Accessing from a german cable provider and cloudflare dns the forum is blazing fast.
Whenever I try to got to these forums, the page loading time is extremely slow. Sometimes I am waiting up to a good 2-5 minutes. Sometimes the webpage just wonāt load all together and I just get a blank white page. I have tested on Mac and Windows and on Firefox, Chrome, and Safari and get the same results. This can be quite annoying at times because I often come to this site to regularly view forum posts and get help. All other sites I visit load in a second or less. My internet download speed is roughly 50-60mb/s and I am located in Australia.
Any ideas on why this is?
It can be that the server is saturated, or it is a bad network connection between the providers. Nextcloud uses Hetzner, you can use a looking glass service to see which way the packages pass and where the bottleneck is: Point in Germany, Falkenstein, data center Hetzner from SpaceCore
Usually they have a pretty open peering policy and present at multiple points in Europe, for overseas they rely on larger carriers (see the transit providers https://www.hetzner.com/unternehmen/rechenzentrum/). Sometimes, end-user providers have bad peering connections to these larger carriers.
We can perhaps get an idea, if you can post the mtr output to your home connection (you can anonymize your own ip, the interesting part is when it reaches your ISPās network).
Iām also in Australia and experiencing this issue. Itās a consistent problem and not something that comes and goes, so I donāt think itās a server load issue. I find it takes minutes to load any pages on the forum as Artichoke1 said.
I can provide mtr output, but could you explain what youāre looking for? My home network to help.nextcloud.com or from Looking House to my home network?
even me being not literally on the other side of the world do experience certain load-problems often causing a 500 error to me. I already filed an issue on GH for it.
youāre welcome to leave your 
there.
If you do the traceroute, there is a first hop at hetzner, like:
core0.fra.hetzner.com (213.239.252.37)
And then just the last hope before hetzner, or if you manage to do the looking glass to your ip, the first hop outside hetzner network.
You can also test and download here: http://speed.hetzner.de/
That is more for the server itself and not the networkā¦
I know. Thatās why I opened this issue there. And we donāt really know where the slowness comes from. Could be as well from gettingt timeouts due to serverproblems.
Download speed for the 100mb file peaked at around 6mb/s and was at least a couple of mb/s for the whole download. Didnāt have any issues with slow starting or anything, so all seems normal.
Hereās the result of mtr to my local network using the looking.house link you posted:

And you can download from the speed server quite ok. Iāve just seen that the loading of some resources either doesnāt work or timeout (especially avatars, either timeout or some take very long like 9s). Not sure if that adds up in a bad way with the increased delay that you obtain much more timeouts. Problem of these nice interactive pages lazy-loading (depending on how much you scroll) works very well for short delays but if the delays are increasing and you have problems, it can be very painful to useā¦
Iām not getting timeouts, everything does eventually load. The problem Iām having is it takes 1.7 minutes from initially starting to load the page to see anything on screen. I had to wait that long to open this up to write the reply (I timed it). Once everythingās loaded itās more usable, if a bit slow. For example I donāt get an exceptionally long delay posting replies and I can navigate around the forums without too much delay.
I looked in the browserās network inspector to see if there was anything specific causing a problem, but itās basically every resource taking a very long time to load. For example, this resource:
Has the following timings:
You can see itās an exceptionally long wait and download, especially since the actual file is tiny.
I tried loading that same asset with curl and the delay was still slow but much, much shorter. Hereās the command (curl-format.txt borrowed from SO):
curl -w "@curl-format.txt" -o /dev/null -s https://help.nextcloud.com/theme-javascripts/fde9bc7c258930129c4085bb1fbd4886a90e5d33.js\?__ws\=help.nextcloud.com
And timings I got
time_namelookup: 0.005279s
time_connect: 0.359582s
time_appconnect: 2.010141s
time_pretransfer: 2.010278s
time_redirect: 0.000000s
time_starttransfer: 2.368495s
----------
time_total: 2.371560s
This seems to be consistent, in that in curl it always takes around 2 seconds and in my browser (Iāve tried several different machines and browsers) it always takes just under 2 minutes. Maybe thereās some kind of cumulative effect happening?
By comparison, the link you posted takes around 5 or so seconds to fully load, which is a little slow, but itās still usable.
These curl commands, I didnāt know, really cool 
For the javascript, for me it is <0.5s from Europe.
However, the strange letter avatars:
curl -w "@curl-format.txt" -o /dev/null -s https://help.nextcloud.com/letter_avatar_proxy/v4/letter/e/d78d45/90.png
time_namelookup: 0.004868s
time_connect: 0.037185s
time_appconnect: 0.143471s
time_pretransfer: 0.143888s
time_redirect: 0.000000s
time_starttransfer: 60.242762s
----------
time_total: 60.243041s
See also: Help.nextcloud.com slow page load times
Iām 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.
Iām really confused why I canāt reproduce the problem using www.webpagetest.org. Timings from that site are consistently and reasonably fast enough, say, 5 seconds or less. So Iām 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 Iām using Firefox Developer Tools but Iām 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 itāll take 2 seconds.
