-----------------------------------------------------------------

This is LOG4NET-421 as well, right?  The reporter included a workaround that may help \
if this becomes an issue before we fix it.

Haven't looked at the patch, yet, but would aim for something like 3 myself.

> If you use a context property in your appenders pattern, there will be a \
> significant logging slowdown. In my experience anywhere from 3 to 5 times slower \
> (this will depend on the appender). I believe that as soon as you use a context \
> property log4net will internally access the windows user name even though it's not \
> the property you want to access. This theory comes from the fact that printing all \
> properties in the pattern (including the costly property username) compared to just \
> printing one will slow down the logging with the same factor. I've made a \
> stackoverflow question with more details as well \
