This is the same jack as for Linux? If so, jack doesn't add latency and
can handle more than enough ports. Latency is from the backend/hardware
and the clients have to provide the ports. Jack doesn't do resampling.
It's impossible to misconfigure jack in a way, that it will add latency.

Much more, on Linux the -Xalsarawmidi switch for jack2, aka jackdmp (not
for jack1, aka jackd) does enable zero MIDI jitter, when using good MIDI
devices, IOW PCI and PCIe devices, USB always will produce MIDI jitter.
