Just some feedback on CZ's ISO and in a live environment

Ever since I discovered that the Ventoy was an abandoned project, I started making bootable USB sticks with Clonezilla and other software (such as GParted) and I noticed some weird differences in performance of Clonezilla. When you upload the ISO on a USB stick using ROSA Image Writer (for example), everything that the program does works 4-5 times slower than when it's installed in a Live DVD of a linux distro, like Debian, for instance.

Here's a summary of the performances based on my observations.

  1. ISO booted directly from a USB stick: • Finding and identifying partitions takes about 2 minutes for that task to be completed. • Packing rate is slow - 8 GB/min tops (z9p; all the storages are 2.5" SSDs, not NVMEs), unpacking is slightly faster reaching 10 GB/min.

This performance was also the same when booted from Ventoy but Ventoy has its own problems. It's likely Ventoy's problems are not the reason for the slow performance but it's not impossible either. Ventoy wasn't designed to work with efficiency cores of a CPU and unfortunately those are the cores it was using, hence the slow performance of everything booted from Ventoy. But given the same performance is observable outside of Ventoy, I'm a little confused as to what's causing the slowness.

  1. Clonezilla installed in the live desktop of any distro like Debian (with the nvidia driver installed in the live distro, so that the desktop can run in the screen's native resolution) and ran in terminal. • Finding and identifying partitions takes 15 seconds tops, no matter how many partitions are there, even if they're 20. • Packing rate works at 14-15 GB/min (z9p), unpacking passes 22 GB/min, sometimes it can reach even 30 GB/min.

My guess is kind of a shot in the dark, altough I can't be 100% sure: when the desktop runs with the GPU driver, that "tells" Clonezilla to use the performance cores of a CPU, skipping the efficiency cores, thus making things work A LOT faster.

Note: this feedback is not me complaining, it's just an observation of different performances that, IMO, should at least be investigated.

My hardware is in no way slow or old. i7-12700F, 64 GB DDR5-4800 RAM, the GPU is RTX 3060 (12 GB), so no ancient hardware here.

Have you tried the method here: https://clonezilla.org/liveusb.php#windows-setup-uefi https://clonezilla.org/liveusb.php#linux-setup-uefi I.e., download the zip file and use native program to do that. No need to use Ventoy or ROSA... Any difference?
