Re: Reg slowness seen in openssl 1.1.1

Hi , I have installed openssl from scratch and there I am not observing any degradation. But I built it with in my project, there I observe the degradation. The Configure file remains same , but still in my project I can see a difference that "dynamic-engine" is present in enabled feature list.

Re: Reg slowness seen in openssl 1.1.1

Hi , I can observe slowness with standalone c programs. Attached are the sample c programs. If I run them with openssl 1.1.1 and 1.1.0e version on Linux system (Linux 2.6.32-504.el6.x86_64 x86_64 ). then I can see the difference. If I increase the number of loop in the program, then the slowness
