Today I noticed that my integration tests with nhibernate were runnning very slow on the build server. Very slow meaning 1 hour to run while they run for 6 minutes on my dev machine all 840 of them. Something was different.
I am using Finalbuilder 5.5 on my build machine and that uses the nunit console to do the dirty work for it.
So I tried running it in the nuint gui tool and there too it was slow.
So I clicked a bit on the tabs, one never knows when one might get lucky and low and behold I was lucky. The Log tab of the GUi builder was getting lots of work.
I know my readers (all 3 of you) prefer pictures over words so here is a picture.
Apparently nunit 2.4.6 has a config somewhere that says log4net should use debug level logging. Which slows down nhibernate like never before.
So I copy pasted my regular log4net nhibernate appender and other config things into the app.config of the test project
```xml <configSections> <section name=“log4net” type=“log4net.Config.Log4NetConfigurationSectionHandler,log4net” /> </configSections>
<!– This section contains the log4net configuration settings –> <log4net debug=“false”>
<appender name="rollingFile" type="log4net.Appender.RollingFileAppender,log4net" > <param name="File" value="nHibernate.log" /> <param name="AppendToFile" value="true" /> <param name="RollingStyle" value="Date" /> <param name="DatePattern" value="yyyy.MM.dd" /> <param name="StaticLogFileName" value="true" /> <param name="maxSizeRollBackups" value="10" /> <layout type="log4net.Layout.PatternLayout,log4net"> <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" /> </layout> </appender> <!-- Setup the root category, add the appenders and set the default priority --> <root> <level value="Info"/> <appender-ref ref="rollingFile"/> </root> <logger name="NHibernate"> <level value="Warn" /> <appender-ref ref="rollingFile"/> </logger> <logger name="NHibernate.Loader.Loader"> <level value="Warn" /> <appender-ref ref="rollingFile"/> </logger>
</log4net>``` and added this to the first test, just to check if it was faster.
And now my integration tests are back to their normal slow self.
I think this problem will not occur in nunit 2.5 and above since they now use a different logger then log4net.
