This looks like the same as #65719. The regression in Unix performance is likely due to the additional error cleanup with OpenSSL.

The regression seems to align with when #65148 was merged.

@bartonjs do we want to even benchmark this? Benchmarking the one shot might be useful, but I'm not so sure about the streaming one.

Apologies for the dup.
