our Team has youtrack incloud (for up to 15 users) and at times it's getting very slow to the point where it's not really usable.
We are using recent versions of Chrome and Firefox -- all to the same effect.
Here is a speedtest I took when youtrack was slow (not super fast but decent download speed). Other sites are loading fast too, so I don't believe it's our internet connection.
Thank you for your support,
