Just wondering why I'm observing all my machines (Mac and Windows, G4 and P4 processors) began taking about 5% longer to run starting with WUs handed out after about 18 October 2006? The science app remained the same, and I don't see any obvious difference in the WU names which would indicate an obviously different kind of of data to crunch. Is it a problem on my own machines?

Examples of recent WUs:

G4 Powerbook (short WUs, which show the 5% increase starting about 22 Oct):

G4 Mini (long WUs, showing increase about 18 Oct):

dual P4 (long WUs, showing increase about 18 Oct):

The time that a workunit takes depends weakly on which data segment it uses. Your WU may have 'changed' data segments at these dates.
