I guess that this may never get to "best performance" for a given app, :and, as such would not want to remove the possibility of tuning. Why are you assuming that tuning takes a lot of effort? One good sysop is all you need. One man-week and then you are done. That's it. We aren't talking about having an entire department working 24x7 for a year tuning machines. We are talking about *ONE* person who tunes the machines on the side. The amount of effort required is zero... That is how it works on UNIX systems... Linux, FreeBSD, Solaris, whatever. Tuning a UNIX box is extremely easy to do and extremely easy to replicate. It doesn't matter whether you have one machine or a hundred. Not taking the time to tune your machines is roughly equivalent to running a 6 cylinder engine on 4 cylinders. This is true whether you are a small shop or a big shop, whether you are a startup or a fortune-500 company, whether your UNIX machines are servers or workstations. There is no 'if'. Anyone who depends on the default configuration of their systems and anyone who isn't willing to maintain them after they've been installed is throwing away money. Lots of money. It's that simple. If your IT department isn't up to the task then maybe you should consider firing them. -Matt :Duncan : :--- :________________________________________________________________________ :Duncan Barclay | God smiles upon the little children, To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
