Expected Behavior vs Actual Behavior

The entire download process takes about 350-400 seconds (about 6 minutes) for a single song (this does not change significantly with a different number of threads).
It is a low-end machine, but the CPU utilisation of Spotdl is only 5%, while the whole system uses about 10% of the CPU.
The RAM utilisation is 5 GB out of 8 GB, so it is not critical either.

Is there a problem/ performance issue/ bottleneck on my side or is spotdl not optimised for low-end machines?

Other (normal) programmes such as nginx and Python applications that use Flask, for example, do not run slowly.
The internet connection is fast enough, as it takes around 12 seconds to download a single song on another PC.

Steps to reproduce - Ensure to include actual links!

1. Get a low end machine
2. execute spotdl --log-level DEBUG --threads 8 "Test drive"
3. Wait a long time
