BIG-IP 1500 Http TPS

Hi there,

 

 

Using BIG-IP 1500 I have a question using HTTP-POST request;

 

Is this equal to the stated performance of 2000 TPS for the 1500 ?

 

Can I use keep-alive option towards the 1500 ? Any difference in performance ?

  • If a client re-uses a connection to a VIP it would be more efficient than sending each HTTP request over a separate TCP connection. Similarly, if you use a OneConnect profile to have LTM re-use serverside TCP connections, it would be more efficient than LTM opening separate TCP connections for each HTTP request. I would assume the sizing numbers are best case estimates of what the platform can handle. Your actual experience will be highly dependent on the traffic patterns and client and server behavior. The best testing method is to simulate your user traffic patterns through LTM to the actual application you will be load balancing.

  • Thanks Aaron, but I feel my questions are still not clear.

     

     

    Some clarifications;

     

     

    1) What traffic profile is refered to when stating the TPS ?

     

    2) Can I use keep-alvie option and, if so, what additional configuration is needed?

     

    3) Can I assume better performance by using keep-alive ?

  • Hi JB,

     

     

    1) What traffic profile is refered to when stating the TPS ?

     

     

    It's a little dated by now, but F5's performance testing methodology is explained in the following document:

     

     

    http://www.f5.com/reports/f5-performance-report.pdf

     

     

    And they've provided suggestions for how to conduct your own testing here:

    2) Can I use keep-alvie option and, if so, what additional configuration is needed?

     

    You can configure serverside keep-alive with a OneConnect profile:

    3) Can I assume better performance by using keep-alive ?

     

    You would get better performance using keep-alives than without. But I'm not sure what exact method was used to determine the 2000 TPS rating for the 1500 platform.
