After noticing a significant difference in results for the himeno test compared to a year or more ago, and narrowing it down to between kernel 4.12 and 4.13, I searched and found this very relevant article. Thanks.

Oh wow, when I saw the I/O benchmarks on 4.12 I immediately wondered if it might solve the bogging down issues during large file transfers with the other 4.10 and later kernels. It did help a bit, in fact I'm actually typing this while transferring a 130GB file which I can't do with any other kernel, no matter the IO tuning. I don't see any transfer speed improvement though.

How can the IO throughput in this article be the best (highest) for kernel version 4.12, when boot time is worst (longest) for kernel version 4.12 based on the article below?

Thanks a lot for this Michael!
Some food for thought: personally, I think it'd be more interesting to have some LTS kernels instead of the EOL ones.
What you have shown here is of course very interesting in showing the progress in a chronologically consistent manner. But, for instance, I'd find more value in seeing how 4.9 (LTS) is doing instead of 4.10, which has been EOLed for 6 months now.
Anyhow, just putting an idea out there. Keep it up!

Linux 4.10 To Linux 4.15 Kernel Benchmarks
Phoronix: Linux 4.10 To Linux 4.15 Kernel Benchmarks
The ThinkPad X1 Carbon has been enjoying its time on Linux 4.15. In addition to the recent boot time tests and kernel power comparison, here are some raw performance benchmarks looking at the speed from Linux 4.10 through Linux 4.15 Git...
