No one thus far has posted real data, so here it is --

Data for Trailblazer Plus (Rev BA5.01 ROMs):

I had been getting consistent 800-950 cps xfer rates for batches on the order of
250K/file with COMPRESSION ENABLED.  After complaining to my (ex-)feed about the
seemingly slow xfer rates, they suggested that I turn off compression.  Now my
site consistently gets between 1100-1350 cps xfer rates, about a (believe it or
not) 40% boost in throughput.
