  • Joomla website is becoming too slow

    Sep 18, 2014 12:34 AM|orphicpixel|LINK

    Hi,

    I have a Joomla 2.5 running on iis8 with fastcgi, I noticed lately that when the visitor reaches to 300-400 simultaneously the website becomes to slow, even the point that it will return a 500 Service Unavailable.

    Restarting the IIS will then solve the issue.

    Can someone help me sort this thing, is there any settings that I missed like setting in the php.ini or in the fastcgi


    And additional info about my problem, when the website encounter error 500, only the php application is not running static html can be opened let say mywebsite.com/app.php is not opening but mywebsite.com/app.html is opening

    first of all, check for resource depletion: do you have enough free memory, is cpu usage high and hwo is disk IO?

    If there is no resource depletion, you might just have to increase the allowed concurrent requests.

    Check you logs for the error 500 substatus http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/64e30660-d2f0-4e90-98cc-1652214a2b93.mspx?mfr=true It will be probaly 500.13, but you better check :)

    If it is 500.13, this nice blog help you troubleshoot: http://blogs.technet.com/b/kennymaita/archive/2012/04/26/server-too-busy.aspx

    Note that no webserver can handle unlimited amount of users. You might need to look into load balancing scenarios.

    Today, we experienced again the same problem, when I checked the running processes, saw that 32 instances of CGI/FastCG (32bit) is running, by end tasking them all, the Joomla website returns back to normal.

    The same process when restarting the W3SVC will resolve the issue

    What is the RAM and CPU usage when you face this issue? Also, did you review the error logs to find the root cause of 500 error?

    Hi orphicpixel,

    You could use the Debug Diagnostics Tool to troubleshoot high CPU usage by a process in IIS,

    Please follow the steps below, I think it’s available for you to troubleshoot this issue.

    Configure Performance Monitor logging

    Disable Debug Exception Catching

    Create a dump file

    Disable Performance Monitor logging

    Analyze the dump file

    For reference- http://support.microsoft.com/kb/919791

    In addition, you can also try Fiddler, it captures HTTP(S) traffic and logs it for the user to review. It can also be used to "fiddle" with HTTP traffic as it is being sent. By default, traffic from Microsoft's WinINET HTTP(S) stack is automatically directed to the proxy at runtime, but any browser or application (and most mobile devices) can be configured to route its traffic through Fiddler.

    Please let me know if there is anything that I can do to help.

    Best regards,

    Angie
