I have a complicated sketch that I want to mirror in several directions. Because it's so complicated mirroring and anything else gets super slow (or crashes). Is there a way to "group" it so that Fusion has a less tough time with it?
Mirroring a complex sketch
Hi! It should work regardless. To add to what @wersy already mentioned, the quickest way to get the mirrored sketch is to use Revolve command to revolve the profiles around the mirror axis 180 deg. Then create a sketch on the same plane and project the faces from the mirrored side. Lastly use Remove command to delete the unwanted bodies.
Many thanks!

As has already mentioned, try and mirror in the solid environment. If you must mirror the sketch, the attached video will give you an easy way. The Surface Normal is opposite from your sketch plane so it mirrors it.

First, I would recommend to scale (calibrate) the canvas to the proper size.
Looking at the canvas, it would then be apparent that all the wall thicknesses are uniform, so "Thin Extrude" feature would help to curt the sketch work in half.
Also, there are multiple symmetries in this object, which would, again, cut the sketch work in half.
Than, as others have already recommended, you can mirror 3D geometry (or features) , instead of sketch geometry.
For example, this is all the sketch you need:
to create this:
