For openssl there is a huge improvement.  I was doing benchmarks on
openssl (they were done for internally at a company I no longer work
for).  We were using P3's at the time.  The highest performance gain was
between i386->i486 for varied ciphers; that is to say going to i586 or
i686 (with gcc2.9x) was not that much better.

Take this with a grain of salt...  this may actually have something to
do with openssl having canned ASM implementations for some ciphers on
some architectures, but I am not sure about that.
