During stress testing in our lab, I am experiencing 100% CPU utilization on my SSL module and am trying to find some definitive information regarding exactly what the SSL module capabilities are with regard to simultaneous connections, maximum traffic capabilities, etc... I have seen a few references to this type of information in these forums, but no detailed information, like a link to supporting documentation on Cisco's website.
What we have is a 11506 running WebNS software version sg0750105s and during our load testing, we have found that when approaching 1,000 simultaneous SSL connections, the SSL CPU is reaches 100%. I am attaching our test script and resulting stats. As you can see, as our load test ramps from 200 to 400 to 600 to 800 and finally to 1,000 connections, until the SSL CPU finally reaches 99% and we then begin to experience dropped connections.
Any ideas on how we can configure the CSS in software to better handle the required SSL connections? Our test requirements are actually for 1,500 simultaneous connections... which we have yet to accomplish.
Thanks for the reply. The 1,000 transactions info is something I have read here previously... but can you direct me to any supporting documentation? I have not been able to find this info on Cisco's website.
Also, are there any software configs that can be implemented to help lighten the load on the SSL module while processing such large transactions?

Usually, we can access ESXi Shell by pressing Alt+F1 from ESXi DCUI (Direct Console User Interface).
But on HyperFlex system, it just shows black window.
This is expected behavior because HyperFlex redirects ESXi Shell output to SoL...
