Someone else pointed this out but it bears repeating since you never
replied saying you had this figuredout.   i don't know whether things will
get compressed or not based on your configuration (-z vs. dont compress)
but try without the -z.  If it *is* trying to compress that could easily
explain the slow speed of your transfers.
