To increase the number of objects being compressed, using an allocator called z3fold.

The two additional improvements we want to implement are: He’s written a more detailed blog post on how he configured things on his personal blog, but we’ll paraphrase them below.

But this won’t yet give the smoothest performance on a 2GB device.įor more advanced users, Dave Jones, who leads the Ubuntu Raspberry Pi work at Canonical, has a few additional improvements to share. The above should already improve performance on your existing 4GB or 8GB Raspberry Pi. If you’re not a confident Linux user then you can stop there. Once you’ve done this you can restart your device and benefit from an increased performance boost! Going further… Since zswap is supported by default, you can enable it with a simple command.Įnter the following into your terminal: $ sudo sed -i -e 's/$/ zswap.enabled=1/' /boot/firmware/cmdline.txtįor newer Linux users, this command is basically a shortcut to edit the cmdline.txt file in your boot folder and set the zswap.enabled parameter to ‘True’ ( 1). It is much quicker to decompress a ‘zswapped’ page than it is to access the swap file so this is a great way of getting more bang for your buck from systems with smaller amounts of RAM. When a process is about to be moved to the swap file, zswap compresses it and checks whether the new, smaller size still needs to be moved or if it can stay in your RAM. Okay, so where does zswap come in? Zswap is essentially a compression tool. You can read more about swap in the Ubuntu Documentation. However, using swap is less performant than using RAM since accessing your hard drive (or SD card) is slower.

This enables you to keep working even when your system is using almost all of your RAM. Swap files act as a kind of overflow for your RAM, caching pages that are rarely used to free up RAM for more active processes. If you’re running any kind of Linux system, it’s highly likely (and recommended) that you have a swap file allocated on your hard drive or SD card. To answer that we need to talk about swap files in general.

In this blog, we’ll show you how to enable this functionality today and benefit from the upcoming performance boost that will come as standard in 22.04. The secret to this optimisation is a Linux kernel feature called zswap. This means targeting a viable Desktop experience on Raspberry Pi 4 2GB models. One of our goals for the upcoming Ubuntu 22.04 LTS release is to lower that barrier to entry. Up until now, we’ve recommended users stick to models with either 4GB or 8GB of RAM to be confident that it will perform well.

However the full desktop environment is quite a lot for the Pi to handle.

Ubuntu Desktop provides everything you need to develop software and even deploy it to Ubuntu Server on devices like the Raspberry Pi Zero 2 W. At Canonical we’re proud to be able to offer a full Ubuntu Desktop experience on the Raspberry Pi 4.
