Currently enabling worker and running a preview slows down the preview loading considerably where it takes about 15 seconds to start, as opposed to loading within a second or two when worker is disabled.
I've noticed big performance increases by using worker, so my question was is the drawn out preview loading time going to be fixed in a future release of C3?
EDIT: It seems the AJAX plugin is still causing issues with worker. I deleted it and then the preview started up like it should.
