I don't want to put words in OP's mouth, but I suspect that OP was referring to just like... "you click and something and then wait" type of slow. Something like, taking several seconds to load an issue.
In my case, we were a small team (<10 users, <1k total issues split in maybe 8 projects), and were running into random load time slowness irritations. It never stopped us from doing what we needed to do, but it sure did make it more frustrating to do it. We are using a cloud instance.
Itβs a documented phenomenon in UX that if an activity involves a quantity of small pauses in a short enough time span, that the user perceives them as a single, long pause.
If your app is fast but your workflows are terrible, people will call you slow because everything takes four interactions. If you have a bad workflow and a slow-ish app, people will talk about you on the Internet.
