Usually async operations happen in engines when they need to talk to hardware but you can still utilize async mechanism in pure software if you have the scenario

Hi all,
I have some queries regarding OpenSSL async operation.
Current setup ------------- I have one OpenSSL dynamic engine (with RSA and AES-GCM support) and linked it with Nginx server. Multiple WGET commands on the client side.
Current issue ------------- Since OpenSSL do_cipher call (the function in which actual AES-GCM encryption/decryption happening) comes from one client at a time which is reducing file downloading performance. So we need an asynchronous operation in OpenSSL ie. we need multiple do_cipher calls at the same time from which we should submit requests to HW without affecting the incoming requests and should wait for HW output.
Queries -------- 1) Is there is any other scheme for multiple do_cipher calls at a time?. 2) Any method to enable asynchronous call from OpenSSL?
Versions ------------- Openssl - 1.1.0h Nginx1.11.10 Wget 1.17.1
Kindly support me. Please inform me if any more inputs needed. Thanks in advance.
