Hi everyone, I've recently recompiled my kernel again, after running the standard debian one, to include stuff such as preemption and a higher tick frequency (1000Hz). It is hard to test whether this makes any noticeable difference on performance, but I've found that it seems to make the desktop a lot snappier. Especially using compiz (which is still having problems on this box, but that's the crappy nvidia drivers). Since I changed a few other things (notably target cpu and apic) I can't be entirely sure that this is due to preemption, but it seems the likely candidate.
Anyway, I'm writing this mail since it's quite troublesome to be compiling your own kernel as a desktop user (even if you know what you're doing) and many people out there seem to be doing exactly what I did, e.g. download debian sources, change 3 options or so and recompile. At least, it comes up regularly on debian-user. Therefore I would like to ask whether people think it a good idea to add a lower latency version of the kernel to the repository. It would then only differ from the stock image in about 3 kernel options (CONFIG_PREEMPT*, CONFIG_PREEMPT_BKL and CONFIG_HZ_*). I don't follow LKML myself so I'm not sure what the general consensus among kernel devs is about the value of preempting. I realise my own appreciation of the subject is quite vague. I'd love for someone to fill in the gaps. greets, Wim -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
