It just looks like a problem of esp driver. When I tested at Nov 2000
(maybe 1.5J kernel), I got the following data,

FreeBSD(K6-200MHz) -> ftp -> NetBSD/mac68k(040-80MHz) -> SCSI drive(3.2GB)
                    約195KB/s

FreeBSD(K6-200MHz) -> ftp -> NetBSD/mac68k(040-80MHz) -> ATA drive(4.3GB)
                    約570KB/s

FreeBSD(K6-200MHz) -> ftp -> NetBSD/mac68k(040-80MHz) -> /dev/null
                    約600KB/s

The taget machine is LC630.
