Description

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.

<jbonofre> cibsen: no special reason
