When yaourt install packages from AUR, he do this steps: [1]. Download archive file with PKGBUILD to install [2]. Extract package and do compile || download & etc [3]. Compress package to install it with using packman [4]. Run pacman [5]. Pacman >extract< files, and install hims. I think if we can remove [3], this is speed up installing || upgrading process from AUR. -- Best regards, Timofey.
