Okay I did some time tests. I have my machine set to 80 inches per minute, accell/decelling at 20 inches/sec/sec. When doing consecutive 1 inch G1 moves, my machine takes .73secs each 1inch move. That's the fastest condition. When I do consecutive G0 moves (with the stop between, but no pause). the machine takes .77 seconds each, so like I said, no cv on rapids is not a big deal. When I alternate G0 & G1, the machine takes 1.00 seconds per move. That means the delay is about 1/4 second.
But if it remains a mystery, I can just look for a smarter dxf->gcode converter. Lazycam doesn't seem too bad...?
