For those of us running antiques:

2x PIII 1Ghz 2G
Running on FreeBSD 6.0beta4 (non-debug kernel)

8.0.3:

N runtime: 1 158s  2 271s  4 567s

8.1beta1 (2005-08-28):

N runtime: 1 85s   2 139s  4 220s


Wow - a huge difference between the versions, I thought the handbrake 
must be on for 8.0.3, but apparently not, all relevant parameters are 
the same...

regards

Mark
