I already cleaned up the token table in keystone DB. I then set up an event to clean that table weekly. Still having the issue. I manually clean table and right after clean up dashboard is still slow.

I noticed that after the token table is cleaned dashboard is still slow, but if I restart keystone service it works fine for a short time. So definitely appears keystone related.

I also noticed in keystone config the expiration time is not set. Should it be set, what impact will it have if it is commented out as such: # Amount of time a token should remain valid (in seconds) #expiration = 86400

Here a previous answer about this issue:

I took those steps, and it is still slow.
