I have no idea what hw you are on, but on my apu2c4*:
tugs$ time sh -c "dd if=/dev/zero of=test.tmp bs=4k count=50000"
50000+0 records in
50000+0 records out
204800000 bytes transferred in 1.495 secs (136960919 bytes/sec)
0m01.51s real 0m00.04s user 0m01.35s system
tugs$ uname -a
OpenBSD tugs.antarctica.no 6.6 GENERIC.MP#584 amd64
Seems pretty damn fast to me.
