Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft Windows XP Service Pack 2.
Windows needs immediate access to paging file contents when it comes out of standby. The Atapi.sys driver must wait for devices that hold paging files to be available when Windows needs them. This causes the Atapi.sys driver to take long time when resuming.
When Windows is resuming, the driver does not have to wait for the disk devices that do not contain paging files. This reduces the time that it takes to resume from standby.
