Yes, you're comparing apples with oranges:
1. Fedora is 4.18.16-300.fc29.x86_64 which has some patches - who knows what - all the distros do ship their own tweaks ontop.
2. 4.20.0-rc5-1.g2ccaf30-vanilla which is the upstream kernel (perhaps?) and does not have those patches.
All this says is that Fedora's kernel is somewhat better, provided the benchmarks are sensible. I have no clue what yours do.
If you want to compare security mitigations, you need to take the same kernel and do two runs, once with the mitigation enabled and once with the mitigation disabled.
with the same kernel, the results are the same, just where it is installed there is no possibility to use other kernels because of the proprietary drivers nvidia. in fedora vanilla kernel, without patches, at least so maintainers maintain I tried to install fedora on this laptop, it works fine even with the kernel 4.19.4 which was at that time
Are you testing Fedora kernel with openSUSE user-space stuff? Or are you testing Fedora user-space?
If Fedora kernel works better with openSUSE user-space, then the point should be either Fedora's downstream patch or the difference of the kernel configuration.
For the latter case, you can try to build the upstream kernel with Fedora kernel config and see whether it works.
I tried to build the kernel with the fedora config, I even wrote about it somewhere above, it works better, but there are still some problems, -- You are receiving this mail because: You are on the CC list for the bug.
