Subject:   CAM performance on -stable

To get an indication of the perfomance of CAM I have performed three make
-j4 buildworld's. Once with the non-CAM kernel and twice with the CAM
kernel. /usr was mounted async,noatime and I used -O -pipe
-DCAM_OLD_TIMEOUT for CFLAGS, NOPROFILE was true

To my surprise all the three buildworld times were nearly identical (3hr
9min +/- 1min). I had expected the CAM kernel to perform much better as it
allows my BT-958 to use Command Tagged Queueing were as the non-CAM kernel
did not.

Has anyone else found similar results on a -stable system?
