You might want to read the article again, OpenSSL 32-bit actually beat OpenSSL 64-bit. The only place 64-bit beat 32-bit was a couple of the MySQL operations.
And while none of these applications seemed to be specially written for 64-bit (I couldn't find any), in many cases they do use 64-bit integers, depending on how the header files worked out. For PostgreSQL (I didn't end up doing benchmarking for that) I actually had problems compiling 32-bit because it kept trying to use 64-bit long long integers. I had to go in an manually edit the header files to get it to compile.
I also went out of my way I think to explain these tests were limited.
