    Checkout the BufferingForwardingAppender. We use this which forwards to a RollingFileAppender. It batches the writes and allows the code to continue without waiting for the write. We setup an Evaluator to force a flush at the WARN threshold and set lossy to false so we don’t miss any messages.

    <appender name="BufferingForwardingAppender" type="log4net.Appender.BufferingForwardingAppender">
    <bufferSize value="512" />
    <lossy value="false" />
    <evaluator type="log4net.Core.LevelEvaluator">
        <threshold value="WARN"/>
    </evaluator>
    <appender-ref ref="RollingFileAppender" />
</appender>
