Could you post your <appender> node for us. What database are you logging to?
According the documentation for 1.2.9 beta, there is a property called bufferSize which writes statements to the database in batches: <bufferSize value="100" /> A similiar property exists in 1.2.0 beta 8. Its very common to declare your loggers like this: private static readonly log4net.ILog log = log4net.LogManager.GetLogger( System.Reflection.MethodBase.GetCurrentMethod().DeclaringType ); I don't think creating a new instance of a logger for each request is the most efficient way to do things. --- [EMAIL PROTECTED] wrote: > Hi, > > I'm using log4net in an asp.net application to log page hits to a > database.
