After reading the Usenix paper on OS performance on Pentium machines, I'm inclined to add optimized code to our libc. Basically, get the processor type (probably via sysctl) and use this to control which versions are called - similar to what I recently did with bzero in the kernel. ...This is fairly low priority, however, so won't likely happen for a few months. -DG David Greenman Core Team/Principal Architect, The FreeBSD Project
