My Mac OS show a weird setup on disk utilily.
I have only one SSD drive on the macbook, but disk utility shows 2 volume groups, 2 system volumes and 2 data volumes.
I think it may be impacting the mac performance.
What should I do?
Reseting the mac to factory setting will resolve it and show only one disk as it should?
thanks!

here is a clean install of macOS 12.4 Monterey by comparison:
Volumes share space freely with the container at no penality
Add, delete, or erase APFS volumes in Disk Utility on Mac
If in doubt look at the mount point:
from Disk Utility.app you can see the mount point
One will be mounted at /System/Volumes/Data this is the one you want to keep,
The other will be mounted at /Volumes and you can simply use the “ -“ to delete it.
You can always erase/reformat/initialize the parent drive if you have a bigger issue—then you reinstall the macOS, then you restore your user data from backup.

By default later versions of macOS now hide the physical drives and hidden Containers from view so you won't see everything as shown in the screenshots provided by @leroydouglas. To reveal the physical drives and hidden Containers you need to click "View" within Disk Utility and select "Show All Devices" so that these items appear on the left pane of Disk Utility. This will give a be better view of the whole entire drive layout. However, later versions of macOS (11.x+) may hide some of the relationships between the various APFS volumes even when using command line utilities which normally reveal everything.
Here are a couple of Apple articles regarding the new drive layouts beginning with macOS 10.15+:
About the read-only system volume in macOS Catalina - Apple Support
Signed system volume security in iOS, iPadOS, and macOS - Apple Support
Somehow, you have not only created a new volume, but you installed an OS on that Volume.
Based on the order, Josh is your startup drive, and you have another named Untitled.
Have you done anything to reinstall the OS?
