Performance in compile task – kernel compile time

Let see if – and how much – compile performances are affected by the I/O scheduler. For this benchmark, I timed the time needed to compile the Linux kernel extracted from linux-3.4.1.tar.bz2 archive.

kernel compile time

As you can see, kernel compile time is basically a function of CPU performance – not disk or i/o scheduler ones. While you can argue that I should left this chart off this review, I decided to include it to show that some workload are not going to be affected at all by the I/O scheduler selection.

Thanks for this very interesting post. Perhaps you could benchmark the different schedulers including BFQ ( next time?
