Please close it if you agree or if you don't feel free to reopen it. > Pattern with Context property causes severe slowdown > ---------------------------------------------------- > > Key: LOG4NET-429 > URL: https://issues.apache.org/jira/browse/LOG4NET-429 > Project: Log4net > Issue Type: Improvement > Components: Appenders > Affects Versions: 1.2.13 > Reporter: Jonas Versén > Assignee: Dominik Psenner > Priority: Minor > > 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 > http://stackoverflow.com/questions/22612286/using-log4net-context-properties-has-negative-impact-on-performance/ -- This message was sent by Atlassian JIRA (v6.2#6252)
