I am currently having issues in all of My SharePoint Environments (Testing,Production and Development ) ,All the pages are taking in between 6-8 seconds to load and for debugging i enabled developer dashboard and observed something called RobotsMetaTag Control Render to be the culprit (Its the same thing in all the environments .I am attaching the screenshot of the developer dashboard which shows a huge spike once it come to the request
Can you please suggest me whats the reason behind this and any solution to that ,Also we have a very robust environments with separate servers for SharePoint Services and Load balanced web front end servers .
I tried to disable the search service and check if there is any improvement in the performance but unfortunately its the same.The only thing i observed today is even one more environment is having the same issue .Can you suggest if i am missing something
One more Update
I went through the ULS logs and for every page request ,i am seeing the below 2 entries in my log files .Does this have any thing to do with the performance?
