HUE renders extremely slow

I recently migrated the HUE database to MySQL as well as the hive metastore database 

and then upgraded Cloudera manager to 5.12 but using a 5.11 components  (so HUE 3.9.0+cdh5.11.1+5073) 
My users have noticed that HUE takes a tremendous amount of time to render its pages
Note cross post on google group hue users
 
I extended the timeout settings and under an incognito window (to ensure nothing is cached) 
I was able to get this message
 
Lock wait timeout exceeded
 
Traceback:
