Certainly possible. We would love to find a way to have the kernel auto-configure this number, but no brilliant ideas have come forward.
When you have parallel hardware (multiple cables, multiple DMA engines, multiple offload engines, multiple CPU cores), having multiple TCP connections can really help.
When you don't (or don't have enough), then multiple connections defeat congestion control and bloat buffers.
Determining the capabilities of the hardware (which could change) is, as yet, an unsolved challenge.
