I have a site running on SharePoint 2013 server having ram of 32 GB. My SQL server has ram of 64 GB. Both have more than 100 GB HDD. When I setup my site it was loaded in 10-12 seconds. But now the opening time for any page is 25-30 seconds. I have checked it with chrome and it shows me following result:
I have cleared log of my both servers. Even I have executed warm up script on my application server. But performance of site is still down. I have googled this issue and found in some blog that shutting down Distribution Catch service might help. But it will stop other functionalities too. So we are not in support of it. Other solution we found was to increase ram for distribution catch. But even that didn't help. As the last solution I am asking for any help or guidance how can I improve the performance?
