Thanks. But no slowdown either? If you have time, it would be nice to see the result for the fork test, which is a lot more sensitive to the pmap handling. The source is at http://permalink.gmane.org/gmane.os.openbsd.tech/38172 Also, it would be welcome if people tested the patch for stability. I have been running it on a build VM for a few weeks, but that is hardly a complete stability test.
