Parallelizing Pacman Downloads I usually start off blog posts with an “about the project”, but this is a very short one so lets just get right into it! You should modify your pacman.conf file to enable parallelization of downloads. It’ll speed up installation of packages that have several dependencies. For all those distro hoppers out there, this should speed up your install times. By default the ParallelDownloads option is set to only 5, but can be configured up any positive integer.
