I've upgraded two PCs from NAV 2009 to 2011. One is an older desktop running a Pentium IV, 2.4 ghz processor with 1 gig of ram, XP Home SP3. The desktop ran a full system scan within a LUA , scanning 305k files in 49 minutes. The second PC is a newer laptop running a Centrino Duo Processor with 1 gig of ram, XP MCE SP3. The laptop ran a full system scan within the administrator account, scanning 407k files but it took 3 hrs and 57 min. The desktop had been running most of the day with the 2011 upgrade before the full system scan was run. The laptop scan was run shortly after the upgrade.
Why the significant difference in scanning time?
