>Release:        FreeBSD 2.0-BUILT-19950603 i386
>Environment:

Toshiba XM-5301-B CDROM (4x spin on SCSI) 

>Description:

I only get 200k/s transfer speed from the cdrom when mounted. But cat'ing from t
he raw-device yeilds 600k/s what gives. Huge overhead on the cd9660 fs? 

>How-To-Repeat:

mount any cdrom on my computer.

>Fix:
        
Workaround: "cat /dev/cd0 >cdrom ; mount_cd9660 cdrom /mnt" Very space taking
though :)
