Maybe there is a problem in newfs(8).

Modified files:
sbin/newfs mkfs.c
Log:
Implement simple write combining for newfs - this is particularly useful
for large scsi disks with WCE = 0. This yields around a 7 times speedup
on elapsed newfs time on test disks here. 64k clusters seems to be the
sweet spot for scsi disks using our present drivers.
Revision Changes Path
1.30 +38 -1 src/sbin/newfs/mkfs.c
When I backout this change, the problem seems disappeared...
