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’s almost definitely not KDE. But we can’t know what it is with the information you’ve given us. We can speculate, and that’s about it.
Speculating is great for troubleshooting. Every time someone speculates a possible cause, it’s possible to devise a way to test it. It’s called hypothesising. Each tested hypothesis, regardless of the actual results, helps to further the understanding of the problem.
