I can't reproduce your findings, at least not on a Core i7-4790K:

type         16 bytes  64 bytes  256 bytes  1024 bytes  8192 bytes
FreeBSD         93454     89077     117328      281016      285456
Ubuntu          93405     88892     114192      122346      120266
FreeBSD-evp    633283    688010     700775      701168      700669
Ubuntu-evp     623889    681075     697211      700505      698460

That was with base openssl 1.0.2p on FreeBSD 12-ALPHA5, and 1.1.0g on
Ubuntu 18.04.
