I opened a ticket about this: kern/181632 Basically, if I do a 'zzz' and then wake the system up, operations like a buildworld or portmaster take much longer after the resume - systat shows very low CPU/disk utilization. It's 100% repeatable, I don't recall this happening on 9.1 I build 9.2-RC3 from source (as I have for years) - this is a fairly generic SMP system (i5 750 with 4 cpus). Let me know if I can provide any data - this is a fairly significant regression for me as I have taken to bringing the system up as needed vs. leaving it on all of the time.
