PLEASE ACCEPT MY APOLOGY!
I have found the problem and it is the app I was using to monitor system resources. As a developer, I should have known to double check this with Activity Monitor.
The app I was using is System Dashboard Pro, available in the App Store. Just now it is showing that Cookie7 is using 383 MB, but in Activity Monitor, Cookie7 is only using 98 MB.
While Cookie7 on the M1 is only using 40 MB, that difference is not at all the same as what I initially reported.
Again, my apologies for the false alarm.
