Manjaro sluggish (installed on USB stick)

Hi all,

for testing purposes I installed Manjaro KDE on a Sandisk Cruzer USB stick (64 GB, USB 3, running in a USB 3 Hub without any other devices plugged in) and the whole system behaves quite sluggish. Opening a terminal takes sometimes several seconds, browsing in the the starter menu is also slow and opening Websites as well. This also happens when Firefox is closed.

I already disabled baloo file indexing and it got better, but it is still sluggish and not really usable.
I also switched off compositing without success and reduced swapiness to 1.

A swapfile is also present (only 512 MB ), but that doesn’t seem to be the problem. Before switching to Manjaro XFCE or even another distro I want to make sure that it’s not just a simple setting which is wrong.

The ISO Image running from a USB 2.0 stick was working fluently, but I can double check this.

Try to have a look at “ALMA”

Just to make sure there’s no misunderstanding. I actually installed Manjaro to the USB 3.0 stick, it’s not just the image I copied there. Is there any drawback of this method that can explain my issue?

Thanks for helping!

“Alma” is optimized for usage with USB (did you even read it ?)


  • try not to use a USB-hub
  • try other USB-ports

thanks, I’m testing a port. And then Alma.

same issue with plugging it directly to an USB 3 port. :frowning:
