The following is my log4j.properties file. It basically logs to a 
RollingFileAppender and to a SocketHubAppender. I have the following issues, 
maybe some of the experts can clarify.

1. Is it true that the A3 appender will actually "see" INFO messages and will 
be evaluated by the A3 before they are discarded by the SocketHubAppender due 
to the threshold set to WARN and rootLogger=INFO? If so, how do I get the A3 to 
only see the WARN (and above) level messages?I still want the A1 appender to 
log INFO though.

2. It it true that introducing the ConversionPattern in the SocketHubAppender 
introduces a processing delay? If so, is there anything I can do to maximize 
the performance of the SocketHubAppender?

3. People in my team are saying the fact I have a SocketHubAppender introduces 
an inherit performance hit with is not seen when we are only logging to the 
RollingFileAppender? Can this be true?

Thanks
Rakesh
