14 Best Lightweight and Fastest Linux Distros for laptops and old computers

Running Linux distro on the old desktop or laptops is really the best option as compared to Windows because of lightweight and fast speed. Although every Linux distro is not lightweight because of high graphical elements. For example– Linux distros those are running Desktop environments with high graphics such as Fedora, Ubuntu OpenSuse, Centos and more. All these Modern Linux distros meant to run on modern hardware. But that doesn’t mean that the lightweight Linux distros we are going to mention here do not have a good graphical user interface but the thing is the fastest Linux Distro are developed to run on the slow processor, low RAM and storage space.

Best Linux distro for old laptops & PC in 2020

You can either go for options like LXLE, Lubutnu, LinuxLite or just install Arch Linux with some lightweight desktop environment. Its all upon you, what we can do is just give a list of Linux Distros those are fast and lightweight and can be used on the old Laptops or Desktops computers/ PC.  Moreover, they can also be proved a good alternative to old outdated computers running on insecure Windows XP.

There are tons of small Linux distros for laptops and desktops but here are some best options for old machines.

Puppy Linux distro

Like its name, the Puppy Linux desktop distribution is small and consumes less space and memory to run; which makes it one of the best lightweight and fastest Linux distro.

  1. Great Article.

    I have a old laptop that i want to use a light version of Linux to use pass around to anyone who needs the web. How can I get it to be in a kiosk mode where after a person logs off all history is gone. This is going to be a shared laptop. Any ideas anyone?


    • Hello Crosby,
      Rather using lightweight Linux os, I would like to suggest your try open source Kiosk operating system such as Porteus Kiosk. Porteus Kiosk is full-fledged dedicated Linux distro that is meant for Kiosk machines. It is lightweight Linux Distro that allows using only the web browser and restricts the user to use any other features or applications. Also, the browser in the Porteus Kiosk is locked down in order to stop someone from tampering the browser settings or downloading and installing software.

  2. Nice article and comparison chart – only one I’ve seen. Keep it rollin! Thanks for the help.

  3. Thanks for the article, but why on earth are you ignoring PowerPC machines? Like 64-bit PowerMac (on G5 processor), or 64-bit iMac (also on a G5), or 32-bit PowerBook on a G4, or older PowerPC machines on G3 processor?

    Please compile a similar comparison chart for Power PC 64 and PowerPC 32


  4. Light weight is one this but what about fastest? I used to run ubuntu 9 and on my server/motion surveilance machine. It seems it would run crazy fast. Now ubuntu is huge and slow. Doing a dd of a 300gb partition to another drive and its taking days. other programs are soooo slow and I see they are only using .1% of the cpu that is basicly idle. Why wont it allocate more cpu to needy or certain processes? Linux has become dog slow compared to the fast crazy software of the 90’s . With the advent of the much faster cpu’s programmers have become lazy using massive compilers that produce huge code. Operating systems no longer parcel out ALL the cpu to processes just a tiny bit. What ever happened to KISS and make it run as fast as you can? I once wrote a program using the bios of the machine to copy one sector at a time from one bad drive to another on a 8086 5mhz machine and it was fast compared to my present amd 4 core of 3ghz and 3 gig ram.

  5. have to agree with Dave. Puppy Linux, for example, used to be super light. 9.5 will install in the minimal footprint listed but the moment you open a browser, even with 1GB of RAM (4x what you listed) and 512GB of disk (frugal-installed) it runs the CPU to 100% and stays there. the many forks of distros are taking their toll on usability on the open source distros
