Maxing out--how do I scale?

[Arild Jensen]

We're running SLES9 with the included CUPS (cups-1.1.20-108.22). We do a fair amount of printing, about 1500 reams per week.

cupsd runs at between 90 and 100% CPU utilization most of the time, running on only one processor.

Is cups really single-threaded? How can I scale CUPS? I've been googling quite a bit and found vague references that CUPS scales, but nothing more than that.
