Sites are running slow

    Question

  • We're running a Windows 2008 r2 server. We have around 220 websites or so. It has an intel xeon e5520 2.27GHz processor and 8 G of RAM. Most of our sites are DNN sites that access a SQL server on another machine with the exact same specs. We are having an issue with our sites loading slowly. I have a custom program that runs on another machine to load all of our sites every 15 minutes to keep them cached. I see that the cpu usage hovers around 30% or so on both machines. My question is, can anyone think of why these sites are loading so slowly? I keep them cached, and the servers do not seem to be overloaded. Anyone have any ideas?

    I should also mention that these servers sit on a much larger virtual server that also sits on a SAN.

  • Hi Michael,

    Thanks for posting in Windows Server forum.

    For the sites loading slowly, it could be any of the following:

    1. SQL Server

    2. Web Server

    3. Custom program for loading all sites

    Have you monitored performance counters to identify the bottleneck? In particular check out the access to SQL server.

  • Sorry it's taken me so long to get back. I read through the article, but I'm not really sure how I actually see/monitor these counters to pinpoint my problem. Any ideas?
