If you’re replying to a community on your home server, all actions should be similar levels of responsiveness, I think replying to another servers community may involve “some” active communication with the instance? Simple way to test this, if you are replying a lot on to another servers community, since you are browsing anyway, would be to just open the server/community directly and click around, if it’s feels a bit slow, then that server is overloaded by a bit and that’s probably the source of your issue. Otherwise we need someone with deeper knowledge in this thread.
