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.
