I don't have a good answer for you other than that it's not endemic to
DragonFly - this is what I got under VMWare Workstation:

1073741824 bytes transferred in 24.643408 secs (43571158 bytes/sec)

 - Which is about 10 times your rate.  I get the same 3.300MB/sec
transfers notice in my dmesg, so it may be something with the
underlying disk.
