openssl speed: any way to test only one curve in ECDSA?

Question

I have been testing ECDSA speed with

openssl speed ecdsa

It took more than 7 minutes to report 22 curves. However, in most cases I only care about NIST P-256 (obviously), so it’s a waste of time for me to run so many niche curves. Is there something like

openssl speed ecdsa/nistp256

in OpenSSL? I checked the manual but didn’t find any.

Apparently, this works:

openssl speed ecdsap256

Thank you very much! I followed this hint and found all the ECDSA algorithm-IDs for speed test. The same source file has IDs for other algorithm as well. I’m sad that this isn’t properly documented. – Franklin Yu Apr 09 '22 at 00:04
@FranklinYu Your link is even more useful for those who try to avoid NIST curves, thanks! I think you should make your comment an answer for everyone to see, and accept yours. – BarsMonster Apr 10 '22 at 00:48
