Single vs. multiple seq client ports

["Tim E. Real" <termtech@rogers.com>]

Hi. Our app currently uses a single alsa midi seq client port
 to address all external midi ports.

I have an opportunity now to change this to allow as many
 client ports as desired, for example one client port for each 
 external port found.

If I proceed, it is possible the user may have many client ports
 if desired.

What are the advantages and disadvantages if any, in terms 
 of speed and resources, of having a single client port versus 
 multiple client ports?

Thanks.
Tim.
