USB Persistence for LL v6.0
Francois:
The laptop was connected to a WiFi network for these. For the following, I disabled WiFi networking and disabled networking (both through the system tray icon checkboxes), then rebooted:

It is more than just the boot process, however: for instance, launching Chrome took over 5 minutes. My installation is fresh, except for installing updates and the NVidia proprietary drivers 515.
Would it help if I ran the same commands with the same drive and computer, but with Linux Lite v5.8?
Thank you for your replies!
Jerry:
Do you use wifi or ethernet?
Francois:
Thank you for you reply. It does not seem like one specific service is the problem:

And this is a benchmark of the usb-data partition:
I'm not sure what that bottom spike at the beginning is, perhaps the boot process wasn't totally over when I launched the benchmark.
Jerry:
Use systemd analyze blame to check boot.

Greetings, Jerry & all!
I've recently installed a persistent Linux Lite v6.0 on a USB 2.0 thumb drive recently, using this tutorial. I had v5.8 on it before and it worked great! But with v6.0... it appears to be much, much slower, to the point of not being really usable. I then tried it again with a USB 3.0 drive, and I cannot see much of an improvement on this 10th gen i5 laptop:
* a solid 15 minutes boot time
* prompts for unresponsive applications when all I did was click the X to close them
* ~1h15 to download ~800 MB of updates on a 40 MBps connection, and 16% install progress after another hourMy thoughts are currently:
* Was there a change from version 5 to 6 that could explain such a difference?
* There's new options when using mkusb since the tutorial was made. Could one of them make the USB drive slower for a persistence purpose?
* Am I doing something wrong or having unrealistic expectations?I tested my USB thumb drive before using mkusb on it. On my desktop Linux Lite v6.0 installation, it took about 10 seconds to copy 1 GB of files to the FAT32 system that was on it then. Also, the laptop's USB port I'm using has 'SS' right next to it.
Any help would be very welcome! Thank you for reading and please have a nice day.
