Long response time for the home page
Posted on 2009-12-27
I'm junior QA engineer in my company, we have a solution for a client that is SharePoint 2007 web portal (internet). 3 web servers, 2 database (active-passive), and one indexing server. The problem that the response time (time for the first byte) for the home page is very long 5-12 seconds. The problem occur for custom CSS as well but in less extent.
We have testing environment (1 application server, 1 database, 1 indexing) and we have the same problem but limited to the main page ASPX file and for 5 seconds. I have made new subsite with default settings and default master page, the response time was great 0.04 second. I have tried to convert the new blank page to be same as the home page gradually by adding web parts and apply the master page, so I have noticed the response time is getting longer and longer.
The problem that during this process the server start to make 2-3 seconds response time for the same page that was making only 0.5 second!!! I have flushed the cache, restart IIS but with the same problem??? the server CPU utilization is less than %10 and the memory usage is normal. As final solution I have restarted the server....and amazingly the response time returned to normal response time about 0.04!!!!
I don't believe that it maybe a full queue because I'm the only one accessing the server, if its the database why its not making this long response for my new subsite? by the way the reset of the page element have very normal response time.
