    Hello,

    We are having seriously slow load times on our site at http://www.okc.biz.  I have tried as many of the optimization tips as I can find and it is still taking 20-30 seconds sometimes more to load a page, the problem gets even worse when loading a news article.  Do you guys have any suggestions?  This is hosted on a dedicated server.  The CPU utilization stays around 60% spikes when pages are loading.

    Thanks,
    Chris Morrow

    Hi Chris Morrow,

    1. Check whether compilation debug is set to false in Sitefinity web.config file

    <compilation debug="false">

    2. Create a sample master page - without any controls on it, css, js. Then create Sitefinity page and associate it with this template (master page). Then access the page and see the response. This will help you to narrow the problem - whether it comes from a page content or it comes from somewhere else.

    3. What kind of optimizations you have used?

    Sincerely yours,

    Hi Chris,

    Important questions first: What version of Sitefinity are you using and what platform are you using (Windows Server 2003 with SQL Server 2005, or perhaps Oracle?)

    Regards

    Hello,

    I'm sorry, I just realize I had a reply on here.  Have been slammed getting our new sitefinity site EastWord.net running.  Thank you for taking the time to answer.

    I have two sitefinity sites running on a dedicated server.  The server is Windows 2003 R2 and running SQL Server 2005.  OKC.Biz is running on Sitefinity 3.5.  Debug is set to false.  I have also enabled ASPNet caching. 

    We do have a lot of articles and content in the database.  In the sf_CmsContentBase there is 6003 records.

    Thanks,
    Chris Morrow

    Three immediate things I can think of that we found is the following:
    1. I checked and you don't seem to have IIS compression enabled. Is that correct? Your home page after caching is about 60.7Kb, compressed that would come down substantially.
    2. Have you got the sitefinity page's Caching enabled? It would depend of course on whether or not caching is an option for you.
    3. Have you enabled your Asp.net trace to see which event in the page life cycle is taking the longest?

    We currently have a support ticket open with Sitefinity to resolve performance issues in general, but there's been no solutions as yet.

    On the one system that we deployed for a customer they're running dual Windows 2003 Standard Edition servers with another server running Oracle 10g and ample hardware resources for each of them. So far the performance leaves a lot to be desired.

    Regards,

    The only concern I have with IIS compression is that since these are media/news site they have almost all dynamic content.  Wouldn't this cause more of a overhead then actually speeding up? (I'm not to familiar with compression).

    Same thing with caching.  Should I cache every page even if they contain dynamic content like articles and images?

    I haven't tried Asp.net trace.  This is definitely something I will look into though. 

    Thanks,
    Chris Morrow

    Hey there Chris,

    On the caching side you're right I'm not sure about the dynamics and how that would be affected. I did ask Sitefinity about Cache injection, but I haven't had a chance to test and prove this yet.

    On compression, it would depend on your server resources. If you have relatively beefy resources available then it might be worth tracking performance on the server for a few days (processor and memory) then switch on the compression and track the performance again for a few days and see if you're happy that the server will be able to handle it.

    One point though... compression can also be set from 1 through 10, 10 being the highest level of compression and it sucks juice from the machine so I wouldn't go that far. Try 9 and then work your way down if your server can't handle it.

    Let me know how it goes.

    Regards
    Jacques
