DELL 2 X PIII/500Mhz, SCSI/Adaptec/(QUANTUM ATLAS)
A couple of days ago, I installed current on a Dell that had been an NT server. Everything works fine except is seems very slow. A make world on current takes over 5 hours. A little more than my old K6-2 300 laptop. This is the first SMP kernel I have used but I have disabled it with no noticable difference in speed. I'm sure that I am missing something very basic. I have attached my dmesg and would appreciate any suggestions as to a starting point to speed it up. Thanks, ed --- The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn and relearn. --Alvin Toffler dmesg.lis0

Thanks, ed -current has lots of debugging on by default. The witness code especially is rather slow. However, it is helpful in finding bugs. You can try disabling witness by building a custom kernel or setting the loader tunable debug.witness_watch to 0. If you really need performance, you may want to run stable instead of current anyways. -- John Baldwin [EMAIL PROTECTED] -- 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 [EMAIL PROTECTED] with unsubscribe freebsd-current in the body of the message
