> Discussion with Claus on IRC:
> <cibsen> any good reason why SMX logging is configured to use line logging?
> <cibsen> thats slow
> <cibsen> WARNING Generating caller location information is extremely slow and should be avoided unless execution speed is not an issue.
> <cibsen> from the log4j manual
> <cibsen> log4j.appender.out.layout.ConversionPattern=%d{ABSOLUTE} | %-5.5p | %-16.16t | %-32.32c{1} | %-32.32C %4L | %X{bundle.id} - %X{bundle.name} - %X{bundle.version} | %m%n
> <cibsen> ah it was lower l which in fact is also slow
> <cibsen> The location information can be very useful. However, its generation is extremely slow and should be avoided unless execution speed is not an issue.
