Although GIMP warned me about creating an image this size, I'm currently working on a project 6000 x 4800 pixels (28,800,000 total) in size. It currently has over thirty layers, and uses 8.3 GB of working memory. That includes 959 undo steps occupying 2.1 GB (I did not realize I'd stored so much!). The stored file size is 66.5 MB, not significant on a 1 TB drive. Working memory limits are more relevant than storage for keeping GIMP cranking along.
I'm working in Windows 10 home on a mid-level HP Pavilion system with 16 GB of installed memory. Currently, with my monster file open, I see 7.20 GB of available physical memory and 8.88 GB of available virtual memory. At this point in my project, which is about 80% finished, saving takes 10-12 seconds. If you are saving after each minor step, this could be daunting. Aside from that, I have not had noticeable lag or problems.
To refresh my memory about that warning, I began a new file that size. The message is
You are trying to create an image with a size of 268.4 MB.
An image of the chosen size will use more memory than what is configured as "maximum Image Size" in the Preferences dialog (currently 134.2 MB).
It might be worth adjusting that setting in Preferences and dialing back the Undo storage. Maybe someone with more systems insight can add to that thought, but the good news is that I'm sailing along while exceeding the default by about double.
