Phoronix: How Ubuntu Laptop Performance Has Evolved Over Three Years From 14.10 To 17.10

With the upcoming release of Ubuntu 17.10, I was curious to see how its performance compares to that of the three-year-old Ubuntu 14.10. Here are some benchmark results showing how an Intel ultrabook/laptop performance has evolved on Linux during that time.

Fwiw, longer compile times do not automatically mean there's a regression. Sometimes they simply try more optimizations.

So essientially Mesa has been improving a lot, ext4 has seen some slight performance improvements and compile times has increased very slightly?

Would love to see a similar test with a older distro on sandybridge hardware

I would love the see the benchmark on Sandy Bridge since I use a laptop that has that architecture. Thank you for your great work!

Could we please also see some numbers about boot time, battery usage... (like, starting with the full battery, how much was left after watching a movie...)

Here's recent boot times comparison from 16.04 to 17.04. Yeah it would be nice to have 17.10 in there too.

Battery use is a good point for the broadwell hardware, not so sure about the SNB though... even if SNB has VAAPI support I doubt it improves the battery life at all. My old i5-3210M uses equal wattage with VAAPI and CPU decoding at 1080p. The CPU is 92% idle with VAAPI, but the fan is noisier, and both give me 4.5h, meanwhile my C720 chromebook with Haswell 2955u gives 7h with 1/3 the battery capacity...

Yeah I think the interesting thing here is to check for battery life from 14 to 17. Did this improve at all?

These are kinda significant gains, wonder where the biggest performance increases come from? Atleast in the gaming benches improved drivers could have an impact

[speculatrix]

I wonder why Lame MP3 encoding changed so much, since it should mainly be CPU bound? Is it that it was built with newer GCC which made better use of the CPU, or, the OS was built with higher GCC optimisation levels?

Lot's of improvements, seeing i965 Mesa did go from 3.3 to 4.5, i wonder what happened to soft fp64 support for r600? It seems to be done but not merged from what I saw (about 6 months inactivity).
