Web Based Configuration GUI - very very slow

I am having an issue with one of my LTM1500 BIG-IP's where the web based management console has become slow to the point of unusable. Pages can take up to 220 seconds to load and sometimes do not load at all without doing a refresh. Load balanced traffic is unaffected - it is just the management console. I have tried 'ping tests' to the IP of the console and they seem fine. Putty and Winscp sessions are also ok - it is just the web interface.

 

Any ideas?

monitoring

    I had the same problem, the URL listed below gave me the clue. It happens with recent versions of Firefox and Safari

     

     

    "...When using recent versions of the Firefox browser, such as 3.5.5, the BIG-IP Configuration utility may render slowly. Analysis of the traffic reveals that the sixth parallel connection that the browser opens has a 17-second delay between the time in which the TCP connection has established, and when the SSL handshake begins. During this delay, the page element that Firefox intended to request with the connection is held up. When this issue occurs, a user will see the Configuration utility begin rendering and then stall for approximately 17 seconds. Eventually, the SSL handshake will complete and Firefox will download the remaining page element. As a result, the Configuration utility will finish rendering..."

    Solution is:

     

     

    bigpipe httpd include '"MaxClients 20"'

     

    bigpipe save all

     

    bigstart restart httpd

     

     

    This is auuming you have BIG-IP version 9.4.2 through 10.0.1
