LTM VE Trial performance problem
I am trying F5's Big IP LTM VE solution using the trial version (10.1.0) to use on my network.
The network configuration is quite simple:
the LTM with one IP, serving 4 Virtual Servers, each with only one real server.
The real servers do not have https, so 3 of the 4 Virtual Servers receive SSL connections from the clients, decrypt it, and send the request as HTTP. Trivial stuff.
I was impressed with the ease that I was alble to configure this, the UI is very friendly and intuitive.
But, When I run some tests the performance results were really bad.
I used Webserver Stress Tool 7 to test the responsiveness of the Big IP LTM and compared to the current loadbalancer I am using, an old Juniper DX, and agains the real server.
Avg response time from the juniper and real server was 4/5 ms over LAN.
Big IP's avg response time was around 8/9 ms over LAN.
I was targeting the one site that does not use SSL at all, all HTTP.
I tried multiple configurations, caching, no caching, compressing, no compression but the results didn't change.
Any ideas why the performance is so bad?
What am I missing?
