loader-messages.log contains many messages similar to the one below
[InventoryStorer]  [Loader performance properties file does not exists in :
C:\Program Files (x86)\Novell\ZENworks\conf\loaderPerf.properties]  
Reduce logging level for the server to be less than "Errors, Warnings, Info, Debug" using ZCC, Device Management> Local Device Logging
The loaderPerf.properties file is used in certain circumstances to affect the way that the ZENworks loader performs. It is not needed in most situations. The log message is merely informing that the file does not exist, so that defaults are being used. The message is only displayed when logging for the server is set to debug.
