Subject: [openssl-dev] [openssl.org #4176] Add support for async jobs in OpenSSL speed
Hi!
This pull request adds support for async jobs in OpenSSL speed:
https://github.com/openssl/openssl/pull/501
Summary of the changes:
* Move the calls to the crypto operations inside wrapper functions.
This is required because ASYNC_start_job() takes a function as an argument.
* Add new function run_benchmark() that manages the jobs for all the operations.
In the POSIX case it uses a select() to receive the events from the engine and resume the jobs that are paused, while in the WIN case it uses PeekNamedPipe()
* Add new option argument async_jobs to enable and specify the number of async jobs
Example:
openssl speed -engine dasync -elapsed -async_jobs 32 rsa2048
Regards,
Andrea Grandi
