Try building without the no-asm configuration option.

Hello,
I’m building openssl 1.1.1g on multiple platforms and I found that the
rsa speed tests are significantly slower in my build than on the other
OS platforms (Linux and macOS).
I downloaded a Windows 64-bit binary distribution of openssl from
https://kb.firedaemon.com/support/solutions/articles/4000121705
<https://kb.firedaemon.com/support/solutions/articles/4000121705> as
they include the configure parameters used for their build.
I ran the speed rsa tests on their openssl Windows 64-bit binary and
they were much faster than the tests on my build.
Here’s some output.
My openssl binary executed with openssl speed rsa:

That is a little over 4 times faster.
Here are my configure parameters:
Configure VC-WIN64A no-shared no-asm no-idea no-mdc2 no-rc5 no-ssl2
no-ssl3 no-zlib no-comp no-pinshared no-ui-console
-DOPENSSL_NO_DEPRECATED --api=1.1.0
And their configure parameters:
Configure VC-WIN64Ano-asm no-ssl3 no-zlib no-comp no-ui-console
--api=1.1.0 --prefix="%openssl-dst%" --openssldir=ssl
-DOPENSSL_NO_DEPRECATED
Both my build and theirs are built with Visual Studio 2015.
Any ideas why my build is so much slower? Is there something in my
configuration that might cause this?
