<br>
we also had to deal with slow dashboard, in our case it was a misconfiguration of memcached [0], [1].<br>
<br>
Check with your configuration and make sure you use oslo.cache.<br>
<br>
Hope this helps!<br>

After kill one node of a cluster which consist of three nodes,<br>
I found that Horizon based on keystone with provider set to fernet respondes very slowly.<br>
Admin login will cost at least 20 senconds.<br>
And cli verbose command return show making authentication is stuck about 5 senconds.<br>
Any help will be appreciated.<br>
