CSS 11501 performance issues when using advanced-balance ssl

hi all,

we noticed considerable longer response times for https-sessions using advanced-balance ssl than accessing the server directly. we use a css 11501 (without ssl module) and in the worst case we see about 3-4 times longer response times with the css than without. the css is just running in testing environment, so there are not many session going through it. is this delay 'normal behaviour' of the css when using ssl-id stickiness? does a higher platform (e.g. 11503) bring more performance in this issue?

Here is the respective config snippet:

===============================

content xxxx

vip address 172.18.26.129

protocol tcp

port 443

url "/*"

advanced-balance ssl

application ssl

add service test1

add service test2

active

=======================

Thanks in advance for any help!

Daniel

Re: CSS 11501 performance issues when using advanced-balance ssl

does it affect every single connection or just some of them ?

Can we see a sniffer trace with the CSS showing the problem and a trace with the CSS.

If possible capture front-end and back-end at the same time so we can see what the CSS does with the client and the server.

Thanks,

Gilles.
