What is different from generic kernel? Why shall I install this one(antix) rather than generic one?

Maybe a thread dedicated to this question should be stickied in one of the subforums.
The forum search results for posts containing "kernel" yields 8,000 (or so, I'm exaggerating) results.
Hey, narrowing it to search posts containing "kernel debian" still found 425+ matches, so yeah, like finding a needle in a haystack.

josef.bunes, I asked the same question, more or less, about a year ago. At least you got some replies.
When I asked... {crickets}, until I persisted, asking 3 times. True story.
In that thread, Helpful Harry did try to point me in the right direction, by chiming in with a single-line post which read "/boot/config-3.7-antix-smp"
(or something like that. Made zero sense to me, at the time, thinking "thanksalot. I already know kernel 3.7 is installed...")

When someone else asked same later, in a different thread, anticapitalista pasted a link to http://kernelnewbies.org

...so I followed the bouncing ball, wheeeee, down the rabbit hole.
Quote:
http://kernelnewbies.org/KernelBuild
If you're trying to see if a bug is fixed, you probably want to duplicate the configuration on your running kernel.
That config file is stored somewhere in /boot/.
There might be several files that start with config, so you want the one associated with your running kernel.
You can find that by running uname -a and finding the config file that ends with your kernel version number.
/boot/config-`uname -r`* .config


On my current antix15 system, it is /boot/config-4.0.5-antix.2-amd64-smp
You can view it in a text editor. The file spans about 6400 lines

To compare/contrast the installed kernel vs "stock debian kernel" or whatever other kernel build, toward deciding
"Why shall I install this one(antix) rather than generic one?"
I suppose you would need to review, side-by-side, their kernel config files (using meld, or kdiff3, or similar program).
Aside from whatever other differences you find, expect to see that quite a few extra drivers for older/esoteric hardware are bundled into the antix kernel.


a related note:
During boot, one of the files consulted by the init script is /etc/init.d/kmod
Here, and in a few other places (vague b/c I'm not yet expert, don't have a full grasp of this) we're able to selectively blacklist modules to prevent them from loading.

another note:
Here's a Loooooooong list of linux kernel boot parameters (boot cheatcodes)

;) or cat 3.16 or 3.17 and look for differences that way.

I wanted to inform that on my Via thin client the Liquorix kernel seems much faster than the antiX kernel. I'm observing especially a difference in how fast I can switch vitrual disktops and how fast web browsing is. I don't know how to measure it in an objective way, if you know - tell me how, but believe me the difference is remarkable. With Liqurix desktop switching, scrolling, link opening goes alsmost instantaneous, with antiX kernel I need up to a second or more. :( I also tested different I/O schedulers on antiX kernel, noop gives a little improvement, but not much. I suspect, that it is the BFQ scheduler on Liquorix which makes the difference. I'll test it with other schedulers, too.

I had to use the 3.7.10 kernel.

The new 4.2.1-antix-legacy seems to work fine for me after a while.

Is this now the best kernel for me hardware?

Thanks.
