I saw a huge perf. increase when we inlined spl's > last year. Right now the mutex API is being somewhat overhauled. When it is done, we may move back to using inlining. If it is a big performance boost on the alpha, then we will definitely inline on at least the alpha. For x86, function calls are (relatively) cheap, so we weren't as worried about it. I am not as aware however when it comes to alpha specifics. Please feel free to knock me upside the head when we do something stupid. > But John is right, you shouldn't be using the ktr stuff unless your > actively debugging something. > > Drew -- John Baldwin -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
