How much preformance gain would we get from a ARMv7 Build? im using the raspberry pi 2 as a plugin devlopment server. Running a recent build of raspbian that was used on my older model B pi.
Well, I'm not too sure since every time I used a pre-built binary on my Odroid XU3, it would segfault. Compiling it yourself has a possibility of increasing performance by a scale of x1.5-3 according to the GitHub readme. Compiling ARMv7 may provide some noticable performance benefits since the RPi2 can utilize the newer features of v7 and correct me if I'm wrong, but possibly NEON.

I would just comment out every flag set line in the CMakeList for PolarSSL and force a set -O2. For some reason even when I'm building the release binary, it does not want to apply optimizations such as -O2. As far as I know, -O optimizations automatically apply -fomit-frame-pointer
