Hello Misaki, Thanks for your response. What you pointed out is exactly what I thought previously. However my test showed that OpenSSL command utility 'openssl' built by my from OpenSSL 1.0.2d source code does NOT utilize the crypto accelerator provided in Sun SPARC Solaris 11.1. I tested the default 'openssl' installed in Solaris 11.1 to verify that the machine on which I run my 'openssl' does have the accelerator. I listed my test results in my previous messages. Now my question is if I need build utility 'openssl' with some special option to utilize the crypto accelerator?
