E9 - Recent Performance - Application Response Time Slowed Considera

I have responded to a lot of these emails in the past on performance issues so now I am stuck and trying to figure out what might be causing a considerable slowdown of the application over the past two weeks after 9 months of relatively decent performance
Â
This is a SQL install with SQL running on its own server and E9 on another server. Progress databases set to read only. CPU usage and memory do not seem to be the issue.
Â
I have not run the SQL disable allow Page Lock script or the index scripts, but could those be the cause of a problem where I had not experienced any issues up until now?
Â
Any thoughts appreciated
