Yes its slow using gcc on board. You can still use NFS for development on the laptop drive, saving flash write cycles. I have used crosstools to build an executable, copy it to the board and run gdb - not pretty, but you can work that way. I would'nt say there's no advantage to using remote gdb. You can set up ddd to remote debug, giving you a good interface.
