Value in adding preempt/RT kernel for x86?

For Developers
1

Are any of the core packages (those included by default on the image) written to be deterministic and thus would benefit from real time kernel support?

2

Not really, networking tasks usually work best without preemption (it won't hurt, but it won't help either).

User trippleflux on github did some work (see here) patching with the preempt/RT kernel and showed in at least one context, much improved bufferbloat.

I built the patch set on my x86/64 box but did not see any differences on the RT kernel vs standard for bufferbloat.

Standard 6.1.40:

normal_kernel
normal_kernel1688×1333 117 KB

Preempt/RT patched 6.1.40:

rt-kern
rt-kern1693×1342 115 KB

Hello @darksky,
trippleflux@github here.

Nice work, the different thing that I am using is, I also using jeverley's dscpclassify works from here.

Perhaps you could retest using jeverley's dscpclassify ?.
