Your test inspired me to test again. I created a 2000 x 2000 image. To create a path, I selected everything and did selection to path. My gradient was the default black to white color options. The gradient width was 500 px.
* Mode RGB (8 bit / sRGB precision): 3:18
* Mode Greyscale (8 bit / sRGB precision): 6:31
The differences in our tests make me think that I must have something off. I don't know what that would be.
