Are there any ways to speed up blender compositor? I have switched companies for a while, while in my last company we where using Fusion for compositing, in the new one we are using Blender.

I find it a bit hard to transition because of 2 main reasons:


The nodes look very messy because of all the squiggly lines and its sometimes hard to follow a path naturally.


The most important one:


Once you start adding a couple of nodes it becomes really slow, it seems to always be compositing something, if I move a node, it composites, if I make changes to a node that doesn't affect the final image, it composites. I like using the software but it can become very annoying.
You can change the lines to be straight by going to "File > User Preferences > Themes > Node Editor > Noodle Curving".





You can disable "Use Nodes" to keep it from updating until you are done moving.
