I am having fun measuring cryptographic operations to determine when investment in Crypto Express cards has any performance benefit for a given workload. https://zvmperf.wordpress.com/2015/03/06/crypto-express-measurements/
If you looked at Crypto Express before, you will know there are different configurations. Combined with different type of workload, there are a lot of combinations to measure. If you have Crypto Express cards installed for use with Linux on z/VM and have some spare moments to collect data in return for fame and gratitude, drop me a note off-list. If you have the hardware installed and would like to use it (or want to verify that it's being used) then I would be happy to try answer your questions and understand what performance questions need to be answered.
