Re: [tor-relays] Running tor on OpenBSD with hardware acceleration

[Farid Joubbi <joubbi@xxxxxx>]

Thank you for the information!
Now I know why.

Do you happen to know if the people on the discussion you linked to came to a conclusion about why OpenBSD relays perform not as well as Linuxes?
Reading the whole thread made me believe that there is probably another bottle neck there too.

Building openssl with such support (using the enable-ec_nistp_64_gcc_128 option when configuring it) would make ECDH much faster."

It's disabled because various compilers produce incorrect code for it
and no one knows for sure which ones are safe to use.
