I got a usecase where I had implemented in Qt4.8.x app on the assumption that slots execute one after another in the order they are connected.

HMI response is slow when continuous data is pumped into my application from other device.
Though we maintain separate threads(threads implementation being derived from Qthread) for reading from the ports and writing onto temporary buffers, HMI is still slow to respond while view switching.

If multiple signals are emitted once, I would like to know if framework would take care of slots execution in parallel or in sequential order.

Thanks and Regards,
