It’s been some years since I have migrated my computers from Ubuntu to Archlinux. This distributions offers some important advantages against Ubuntu.
- Rolling release: this is always referenced by Archlinux users but you only know what that it means after some time using it. I’ll summarize it with: no reinstallations, period; you always have the latest versions of the software available, usually after a few days after its release.
- The best documentation page: The ArchLinux wiki page is simply the best resource available to find clear, vast and updated documentation for every part of your system. It doesn’t matters if you use another Linux distribution, this page is for you as well.
- Unified software repository: do you know what PPA are? Then put all the packages available on PPAs into a unique, user ranked, community-maintained repository, and that’s what AUR is. In AUR you will find more software that you could think of. Until today, every single time I needed a piece of software it was available in there.
So back into the topic of the post, I usually make two changes on how packages are installed on my computers, they are quite simple but really helpful.
By default to build AUR packages from sources, ArchLinux uses only two cores. So if your computer has more than that, it’s a good idea to take advantage of all of them. In order to do that you have to edit the /etc/makepkg.conf to change the MAKEFLAG -j to be equals to the number of CPU threads.
sed -i 's,#MAKEFLAGS="-j2",MAKEFLAGS="-j$(nproc)",g' /etc/makepkg.conf
Again when installing packages from AUR, those packages got built on installation time by default Archlinux creates a compressed archive to save disk space. This slows down installation for packages that are big, i.e. Google Chrome, as before installing the package it compresses it into a .xz file. So I usuallly remove the compression step.
sed -i "s,PKGEXT='.pkg.tar.xz',PKGEXT='.pkg.tar',g" /etc/makepkg.conf
Hope these tips come in handy, and if you know any other suggestion do not hesitate to start a discussion on twitter!
