The sites load slow and especially the data views are loading very slow.
I followed "How can I speed up the Site Performance?" but it didn't work for me.
What else should I do?
It's an intranet. There is one site collection with one web app but it includes a lot of subsites. There is over 1000 users.
Data views are get the datas from another server. But loading the pages ,that includes data view, takes at least 4-5 seconds. One page includes one data view with 1500 rows, not multiple data views. When I try to filter it or go to next page of data view it takes at least 6 seconds. I check the times from the slowest page at central administration.
Other pages that don't include any data view, loads pages slow too but when they refresh, it loads not slow. But a data view page loads always slow.
