SyncScan, Full Cylinder Reads and FSG Cache hits could all impact CPU time for a query.
The query itself being cached would probably not impact the CPU time logged in AMPUsage by any noticeable amount as AMPUsage only logs the AMP
CPU usage not the PE CPU usage. The PE CPU usage would be where you would be saving the most CPU by having a query cached (no need to re-parse the
query).
