Three questions (yeah, you forbided ask, but ...)

1) Why 64

64bit code on SPARC is slower, because SPARC uses 4byte instructions and
processing 64bit data needs more instructions. It is good only if you
need more then 4GB share memory. When you use sunstudio compiler with
best optimization 64bit application has 1%-5% performance degradation.

2) Why you don't use package

You can use Solaris'es packages, which are integrated and optimized for
Solaris.

3)  Why you don't use build-in libssl?

Integrated libssl is not only copy of original open ssl. It has lot of
improvements and it uses crypto hardware accelerator if you have it (for
example Niagara 2).
