You can download a cached copy of the paper from the following address: http://citeseer.nj.nec.com/112654.html The first half of the paper mentions some interesting implementation details that Waldspurger didn't; the second half contains a bunch of benchmarks that are not particularly well analyzed. It looks like the code is available from the author's website, with a 2.5-yr-old port to 4-STABLE. http://www-2.cs.cmu.edu/~dpetrou/research.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
