I have this strange observation under 3.0-current:
dd if=/dev/wcd0c of=/dev/null gives about 2MB/sec
Mount the CD and then
dd if=somefile of=/dev/null gives about 70K/sec
Doing the same on 2.2.2 gives 2MB/sec / 1800K/sec...
What have we done to degrade cd9660 performance that much ????
(to make things worse the -current machine is a 233Mhz P6 and the
2.2.2 one is a 100Mhz 486, same IDE cdrom on both)

Even more code to hack -- will it ever end
