Comment (by sickness):

 so I've tried the gateway and storage server (and also the introducer) all
 three on the same western digital my book live embedded box, tried to
 upload a bunch big files with 1:1:1 encoding just to see how it performed,
 the sum is it upped 2281Mbytes in 49minutes40seconds, so it's less than
 1Mbyte/s, for the record, just running the storage server on the same box,
 with the gateway on another box, averaged 3Mbyte/s, and just copying files
 with scp on this box averaged 8Mbyte/s, I'll paste here the details of an
 upload from the gateway status page:
