Just reporting my own experience.  I bought Macrium (1 device) for my Windows 10 desktop.
Creating a Rescue disk on a Sandisk SD key took about 15 minutes.

On my wife's Windows 11 laptop, using the same type of SD, the Windows 11 system took 3 hours to create a Recovery drive.

Do these times seem about right?
Why the big difference?

I do both kinds of creating a Rescue boot on SanDisk flash drive (based on WinRE 11, NOT PE), and on another system based on WinRE 10, and the time to build the Wim and copy it to both the boot menu and also to the flash drive is less than 10 minutes including also copying the Wim as an ISO file to my repository system and to the second partition on my flash disk.  I maintain it that way so that if I ever have to restore the jump drive to an earlier version, I can do it easily on any system that can manipulate the flash drives files and/or copy from the repository system.  

I wonder if, on your wife's laptop, that a portion of the time was downloading the WinPE components (one time only).  That's not an issue if you use WinRE like I do.  (I want to have the WiFi capability that WinPE does not offer).

As it turns out, after 3+ hours the process completed with an error message.  I tried over again and after another 2.5 hours it finally completed.  22 GB on a 32 GB SD stick.  Must be the entire OS, unlike what Macrium copies.

When you say "Recovery drive", are you talking about Reflect Rescue Media?  I ask because Windows itself has a "Recovery drive" that is a completely separate thing, so terminology can be important to avoid confusion.  A Rescue Media build should be 800 MB, give or take, depending on WinPE/RE version, drivers that are included, and some other factors.  It should not take very long to copy that onto a flash drive.  However, if the Rescue Media file set had to be regenerated, and especially if WinPE files had to be downloaded from Microsoft, then that can take longer.  The more information you can supply, the more likely others will be able to help.

Okay -- I think you're using terms that mean something entirely different than usual on this forum. 
Creating a recovery disk is the process where Reflect can create a CD, flash drive, or ISO file that will reboot this system with a minimal OS (WinRE or WinPE) with Reflect embedded in it, so it can be used to boot the system and when you can't boot the system drive and restore it from an image backup.
Your reported 15 minutes is a bit long, but not excessive

Then you said

On my wife's Windows 11 laptop, using the same type of SD, the Windows 11 system took 3 hours to create a Recovery drive.

I took this to mean you were trying to create the same kind of Rescue Media flash drive. 
But I now think you're referring to creating a backup drive or what we call a CLONED drive.   Is that what you are doing in both cases?  What software is being used for both?   Please be very explicit. And spell out what YOU mean by a "Recovery Disk" and a "Recovery Drive". 
Edited to add:  I see that @jphughan replied while I was formulating my reply, but I think you can see that we both were confused by your original post.
