At ~175 MB with a blank drawing open, I've seen worse.

Some things I noticed about the menus (on Windows):

- The menus don't have hotkey support (Alt+…)

- The File menu is missing a Close option

- Submenus swich too soon on diagonal mouse movement

I'd suggest switching to native Windows menus. From other Electorn apps it seems this should be possible. I'm sure a way can be found to make the menu search feature work, too.

Another small note: on Windows, the close confirmation has the newer multi-option layout, the same you'd get when overwriting files in Explorer, but it only has an option to save changes. There is a cancel button, but that should really be an option.

Edit: memory measured with:

    Get-Process -Name "draw.io" | %{$_.PM} | Measure-Object -Sum

I don't know if that's the right way to go about it.
