Re: [LAU] what's the difference between debian and ubuntu

Hi I've been running debian for years, and was very pleased with it's performance. However, for other reasons (mainly 6 months release cycle), I recently switched to ubuntu. Although I think I have everything setup the same (realtime kernel, /etc/security/limits.conf and chrt of irqs), I can't get the same performance as with debian. Before we start pulling my system apart and I post half the content of /etc/, can anyone think of what might be different enough to cause realtime problems? Anyone else having the same feeling about debian vs ubuntu? I realize that gnome vs openbox and the usability-enhancing-daemons in ubuntu (network manager, power manager, plugin-detection-of-usb, stuff like that) might be making a difference, but my realtime setup under debian was rock steady, 0 xruns while compiling kernels, checking email, whatever. Under ubuntu it's generally good, but every few minutes something creates dropouts, or chopping up of the audio stream.
