![]() ![]() Set commit=15 #Ĭommit data every 15 seconds, instead of the default 5 second time. Do this only if you can do without this information and only with created/modified time-stamps. Use noatime #īy adding this parameter to the fstab, you will tell Fedora that it doesn’t have to store the “last accessed time” for files and folders. ![]() It definitely improves performance and responsiveness of the system greatly. This obviously depends on the amount of RAM your machine has, and of your use-cases where /tmp gets used a lot. This is done by adding the line: none /tmp tmpfs defaults 0 0 ext4 defaults,noatime,commit=15,data=writeback,barrier=0 1 1 We will be adding parameters only for our root partition, after the defaults parameter, so for example my fstab looks like this. You can edit the /etc/fstab file with any text editor. After applying these tweaks there was a big boost in system speed, however again, please be careful with these parameters and sudden power loss. This is mostly where we will be doing performance tweaks. There is also another scheduler elevator=deadline which is also used often with solid drives, so you can try it. Personally I haven’t noticed a big difference after applying this in day to day use. Is said to improve SSD performance so be sure to add it to your kernel parameter list. Data loss or file system corruption in a scenario like this is probable. There is some stuff you can do.įAIR WARNING: These instructions and parameters assume you will never lose power or abruptly pull the USB drive out. While the performance isn’t half bad, you will run into some bottlenecks because of the USB drive speed. The Whisker menu looks and works great! I absolutely love it! Optimizing # The amount of available widgets (be sure to tick the XFCE goodies checkbox in the installer) is huge. You can run GNOME programs, KDE programs, whatever. It’s fast, it looks pretty, it’s compatible with everything. The ease of customization is unbelievable. Why oh why, haven’t I tried XFCE earlier. It’s also very important that you choose a light desktop environment. Boot-time is very fast (10 seconds at most) and the system is responsive and works nicely after that. Obviously Crouton will work much faster because it is running in the included, much faster SSD. After installation is done, you can boot your Chromebook into legacy boot mode (see the Chromium wiki for model specific instructions) and it will boot from the USB drive straight into Fedora without any further tweaks or modifications. Be sure to choose ext4 file system for your root partition, as we will be doing some performance tweaks later on. It took about 90 minutes on my USB drive. Since the write speeds are low, don’t expect the installation to be done quickly. Anaconda on the netinstall image will also ask you what package groups you want, and it will obviously set everything up for you so it is much easier this way. If you want maximum compatibility then better choose the i686 image since it will work anywhere. Also, be careful about which architecture you choose. Writing on the drive is slow, and updates will take hours, so it is much better to use netinstall ISO image from another USB drive (even 512MB one will do) so you don’t have to update it immediately. Now, I strongly, strongly advise that you use the netinstall ISO. You can also run it from an existing Fedora installation or from another USB drive (which I did). While this is fun, and I will definitely try it in the future, much easier way is to use Fedora’s installer Anaconda. You could install Fedora from an existing Fedora machine with dnf with the command like this: sudo dnf -releasever=23 -installroot=/mnt/usb-drive-you-mounted-here groupinstall "Fedora Workstation"īut then you have to setup GRUB, the kernel, users, fstab all manually. I went for the 32GB version, and I created one 8GB fat32 partition which gets recognized first if I put the drive into a Windows machine. It’s also worth mentioning that you will do just fine with a 16GB drive. The drive gets a bit hot under load but nowhere near uncomfortable. The performance is mostly as advertised, I am getting about 95MB/s reads and around 15MB/s writes which is mostly fine for running Fedora. ![]() It’s made of metal and it sticks about a centimeter out of the USB port, so it doesn’t get in the way at all. I went with the Kingston drive because it was available in my country while SanDisk wasn’t. Sadly there aren’t that many options, there is the SanDisk Ultra Fit drive and Kingston DataTraveler micro 3.1. I wanted to get a nice and quick USB3 flash drive which had low-enough profile so it doesn’t stick too much out of my Chromebook’s USB port. Because I didn’t want to mess with the complicated ChromeOS partition structure I decided to install Fedora to a USB flash drive. I wanted to try running Fedora outside of chroot on my Chromebook. MaRunning Fedora off a USB flash drive (performance tips) ![]()
