I have two laptops, I’ll call them laptop 1 and laptop 2.
Laptop 1 is my gaming laptop, and laptop 2 is a very low-spec one that I use as a jellyfin server. Here’s the neofetch result for both of them:
Laptop 1
Laptop 2
The problem
On both of them, I copied a 5GB folder from the laptop to my 3.0 usb flash drive, I used this rsync command on each:
rsync -a --progress folder_path destination_folder_path
| Laptop | Average transfer speed |
|---|---|
| Laptop 1 | 9MB/s |
| Laptop 2 | 45MB/s |
How is this possible? The Laptop 1 is way superior than laptop 2. The laptop 1 has an nvme SSD while laptop 2 has an old 320GB HDD, yet the transfer speed difference is insane.
Does KDE affect the folder copying somehow? If I copy a file on the same SSD on laptop 1, the speed reaches more than 400MB/s.
What is going on here?
It sounds almost like it’s falling back to USB2
You could try copying the same data under different circumstances.
How about to another location on the same disk? How about to a location over the network via wifi? If possible, the same test over a wired connection? If you have a flash reader and a card, try that too?
These will help rule in or out USB as a contributing factor.
Edit: further, you could boot to a live image to isolate whether it’s a software issue or a configuration issue vs hardware.
