Just annotations of little "how to's", so I know I can find how to do something I've already done when I need to do it again, in case I don't remember anymore, which is not unlikely. Hopefully they can be useful to others, but I can't guarantee that it will work, or that it won't even make things worse.

Liquorix kernel seems more responsive than Debian's default

Posted 05-28-2014 at 10:46 AM by the dsc

I'm somewhat skeptical of the tuned-kernel movement, so I didn't install it expecting to make my OS "fly" or anything. It just happened that recently there had been some weird kernel error messages ("perf samples too long"), and, related to that or not, the OS would become sluggish with lots of read-or-write activity (on my old HDD that must be really slow, to add to sluggishness). Apparently you can sort of solve it in a sysctl-like way, printing a "0" to some file/parameter, and it has to be done every time according to the post I've read, but I find weird/suspicious that there's no config file for that, that it has to be generated. As I had found it weird I thought about trying Liquorix again, which I had used before, not noticing any tremendous gains (I think that at that time it made the sound work/work consistently, though).

After one day of "testing" incidentally by normal usage, there were no more "perf samples too long" (I don't know whether the error isn't there or it simply isn't shown on dmesg anymore, though), and seems that the sluggishness episodes have been fewer and shorter.

Before installing Liquorix I saw a curious benchmark on Phoronix, where ironically Liquorix had somewhat significant better performance on some server-relevant tasks, where losing a little bit in some "gaming"-relevant tasks! The "server relevant tasks" were related to disk-access (disk access itself, and, I guess, because of it, static web-page serving).

That wasn't even the same kernel version I've installed, so perhaps it's not even relevant, it seems those are things that change from version to version.

It seems that the "git" kernel performs even better, though. I just don't know if it's a good idea to have it, I guess Liquorix is somewhat better tested/more widely used, but I really don't know.

    I'm just happy this even boots on this P3 IBM T23 and supports everything I have plugged into it.
