I just copied the movie to a USB3 flash drive to rule out LAN as a root cause.
Again, I started the movie and played it for 28 minutes (8.0.1k).
I had 7 skips in that time.
This is clearly less than over LAN, so my conclusion would be that NFS has am impact too.

Can you apply this patch to afl1's build?
I had significantly less skips in that build, so your patch might just be the edge it needs?

I realized yesterday that I don't understand how LE patches work and after fixing that I found out the regular builds have 3 out of 4 chunksize patches already. So the big difference between that and the regular build is fq_codel for networking.
Can you give this build a try? Here's the matching source code. That adds the missing chunksize patch and includes PR 12110, PR 12074 and partially LE PR 713.
I will, but it is based on kszaq's build, right?
So I would compare the performance to 8.0.1k over NFS (25 skips in 26 minutes)?
Yes, it's based on kszaq's latest sources, which currently match his '8.0.1k' build. '8.0.1k' already has the increased chunksize for nfs, so if there is a difference it would be networking related. But that's on the input side, I don't think problems there lead to frameskips, but I'd love to be proven wrong
After 1h 15min not a single skip played from USB with afl1's 8.0.1k-l, not even from opening PlayerDebug or overlay.
This makes me want to test this build via NFS again.
I only played the file via NFS on 8.0.1j-l (5 skips after 42 minutes).
afl1: were there any changes between 8.0.1j-l and 8.0.1k-l regarding frame skips or network performance?

There are no network performance modifications. I only changed late frame management. After my investigation I realized this procedure is trying skip frames already output from decoder. I relaxed criterion for late frames ( 0.98 -> 1.9). Too much relaxing this value can cause a/v out of sync. I also increased measurement window for VSyncOff (30 frames -> 120 frames) to attenuate value changed and eliminate frame skipping.
afl1 If I understand correctly these patches are already uploaded to your report, right? I'd like to use them for my next build.

Movie has been playing via NFS for 1h 12min now, not a single skip!
Things are looking good!

You did apply those changes between j and k?
So it makes sense that k performs better than j or is it just a coincidence?
I have nexbox s905x and I installed [8.0.1k] LibreELEC 8.0 builds for KI Plus / KII Pro in nexbox but ok button of my nexbox's remote is not working in nexbox a95x kindly help me to sort out/solve this problem...

They are included in k version.
