I've had some similar issues working with large images, here's some things I've found.  First of all, if your image is in 16-bit precision, your operations are going to be slow.  GEGL is apparently optimized for 8-bit int and 32-bit float, so paradoxically you'll actually get a much smoother

This morning I saw the new RC was out, and just to do a quick check on performance I downloaded it on my work laptop, loaded a large (~40MP) image, and did some quick operations to see how things shook out.  Everything was pretty smooth, even better than the current stable version on my
