Actually openssl is one of the few packages where it makes a major difference, which is why both WBEL and RHEL include both an i386 and a i686 package. Big enough performance difference I could build the i686 package from my hotel normally, but the i386 package sits so long during the regression tests their NAT box kept closing out my ssh connection. Finally had to use nohup and let it build in the background. Openssl has hand tuned assembly for the i686 platform but other platforms have only the stock C codepath. -- John M. http://www.beau.org/~jmorris This post is 100% M$ Free!
