What exactly does FastL4 profile do?

Customer have to load balance a webserver. Using default settings it takes more than 10 seconds to completely load the webpage. After using the FastL4 profile it takes only 3 seconds. So what does it do to speed this up?

 

We tested also the Fasthttp profile but some objects in the webpage cannot be loaded. Is there any limitation for this profile?

 

Thanks a lot.

    Hi All,

     

     

    I'm new to F5 and wondering if it's worth using FastL4 to loadbalance SSL traffic on 2 web servers, no offloading required but SSL persistence is a must. We have a pair of 2 LTM1600s.

     

     

    Thanks in advance

    Hi Sev,

     

     

    To use SSL persistence you must use a TCP profile on the virtual server. TMM doesn't check enough of the packets to inspect the SSL handshakes with a FastL4 profile.
