My initial post was cut-off and it did not show the rest of info. Don't know what happened there.

I wanted to show that my test system for 1.2rc1 is running 1x1.4GHz and 5Gb RAM. It's a fresh install and it has no job history. cupsd pegged the CPU for 12 minutes while its loading. If I restart it, it does the same thing.

Our production system(secondary) is running CUPS 1.1.23 on a system of 2x2.8GHz and 1.5GB RAM and it loads the same amount of printer queues in seconds, not minutes with very minimum CPU load.

Just my observations...

Thanks,
