What is it? You left off the URL. Looking on the site, it's not posted to the front, and the search function does not locate the article. To answer your questions, you'll have to provide more information. A Linux patch number doesn't cut it. I expect that this is talking about exec pre-forking; if so, then yes, it can yield some minor speedup, but you should not expect much in common applications which fork and do not exec (e.g. Apache). There are a number of micro-benchmarks that could make this approach look good, though... -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
