Phoronix: Early Linux 4.14 Kernel Benchmarks Are Looking Promising

I've begun running some Linux 4.14-rc1 kernel benchmarks and in some areas there appears to be nice gains with this in-development kernel...

It is more like ext4 improvement.

Maybe so, but the file system is about the slowest link in the chain when it comes to performance

The speed is looking nice.

Nice improvements. Looks like we get a great LTS kernel.

Plus, now with -fomit-frame-pointer, improvements to the block layer, and CPUfreq improvements. To quote from the block layer update:

"- Improvements to the IO stats tracking for blk-mq from me. Can drastically improve performance for fast devices and/or big machines."

Doesn't say in the test results which I/O scheduler was used though. Might be worth adding to the info for reference.

It's always included by default in the system tables... In this case, shows NONE for the scheduler.

I was wondering what the NONE stood for. A little label would have been helpful. Thanks for explaining it though.

These are not minor improvements. Makes a little suspicious - is there a good reason there's so much of an improvement?

Well, maybe…
