Is there a measurable difference in CPU performance between Gentoo and Raspbian?
With Gentoo you use different compiler flags and with the USE flags compile only what you need. In Raspbian all software is precompiled.
Because the Raspbian is already compiled especially for Raspberry Pi, is there a real difference in performance or is the only benefit to customize the distribution for your need?
I ask this question, because I struggle again, which distribution I should choose. I'm familiar with both distributions.
