tl; dr: Recompile everything with FP set to hard instead of soft. softfp was a compromise for a number of years but since we are mostly in the age of Cortex now for mobile/tablet markets, it should be possible to recompile the entire toolchain, kernel and apps for a significant speedup anywhere FP is used: 3D, OpenGL, OpenSSL etc.. However, binary only blobs such as 3D drivers need to be recompiled.
