I an not an expert; however, based on material reported here: In terms of perforance, ULE and BSD are equivalent on UP machines - BSD works better in some cases, ULE in others. If I had to put money down, I'd give a very slight advantage to ULE. Measured by stability, ULE is a moderate win. Absent specific cases to the contrary, one reason to go with ULE is that it where future development is focused. That's not to say BSD is being kicked off the train, exactly, just that it won't be the target for the latest and greatest. More qualified voices will please tell what I have remembered wrong.

Re: How to switch scheduler on 7.0?
Hi! Thank you for your answer. So, I need to recompile the kernel. Fine! At first I thought there might be a switch somewhere, to do the conversion The soft way, but OK, I'll rebuild the kernel. Daniel I would like to switch scheduler on my FreeBSD 7.0 box but I don't know how to do that. The scheduler by default has terrible performances under KDE/Gnome and I would like to test the new one. See the following for building a custom kernel: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html You will want to use options SCHED_ULE instead of SCHED_4BSD in your kernel config.

Re: How to switch scheduler on 7.0?
Hi Robert, The expression terrible performances was maybe not the best way to express myself. My intentions were not to step on anyone's toe or being nasty. Sorry about that. To describe things shortly, the problem is responsiveness. I have been running FreeBSD since 4.7 and never experienced what I am experiencing now: - Bad responsiveness of the desktop - Temporary freeze (10 to 30s) - Slow mouse (and not a very smooth movement, a kind of 'step by step') etc. Daniel I would like to switch scheduler on my FreeBSD 7.0 box but I don't know how todo that. You will want to use options SCHED_ULE instead of SCHED_4BSD in your kernel config. Am I correct in remembering SCHED_ULE /is/ the default for 7.0+? If this is true, and you (the OP) do not need the machine for production, there are people who would be interested in hearing about your problems - especially if you are prepared to define (and document) terrible performace and help diagnosing the issue.

Robert Huff It may be the X drivers you are using. X is a bit goofed up in the latest version running on 7, and the drivers seem to create interrupt storms that tie up a system. You may want to test in X and not in X performance. -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Hi! I would like to switch scheduler on my FreeBSD 7.0 box but I don't know how to do that. The scheduler by default has terrible performances under KDE/Gnome and I would like to test the new one. What made you believe it is the scheduler? I googled and read comments of people having the same kind of issues than the ones I have. Their conclusion: The scheduler. I wanted to switch scheduler to see if they were right or wrong... ;) Daniel ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

No. It was at one point planned to be but re@ and others decided it hadn't had enough time to settle in the tree for the 7.0 release. AFAIK it will be the default for 7.1.

SCHED_ULE is slated to be the default in 7.1, IIRC. -ryan ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

The scheduler by default has terrible performances under KDE/Gnome and I would like to test the new one. In light of your message, I was provoked to switched my workstation at work to using the sched_ule thread scheduler. I do not have remote access set up via a graphical interface, so I can not test anything yet as far as KDE is concerned.
