The slowdown is because NUnit captures all log events so that they can be displayed in the Gui. This takes place at the level of NUnit's own Appender, since we can't interfere with the overall level of logging for the app.
In NUnit 2.5, the capture occurs under the console runner as well as the gui, even though it is only actually used in the gui. With NUnit 2.6, due to a previous bug fix, we no longer capture logging at all under the console runner. Under the 2.6 Gui runner, the delay was still occuring. This is because NUnit's default level for it's own Appender is 'Error' rather than 'Off'. In order to fix this bug, the default has been changed to 'Off' and the slowdown will only occur if you actually turn on logging. Note that the test config file controls which log events are _sent_ to the gui, while the gui settings dialog controls which received events are displayed in a particular tab. -- You received this bug notification because you are a member of NUnit Developers, which is subscribed to NUnit V2. https://bugs.launchpad.net/bugs/761579 Title: Tests using log4net run very slowly Status in NUnit V2 Test Framework: Fix Committed Bug description: I've recently been upgrading some tests from NUnit 2.2.8 to 2.5.8 and noticed they were running a lot slower with the newer version of NUnit. I managed to narrow it down to their usage of log4net. For example, the following test runs in 0.06 seconds on my machine using 2.2.8, but with 2.5.8 it takes 4.5 seconds. This is using .NET 2.0 on 32-bit Windows 7. [Test] public void Test1() { log4net.ILog logger = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); for (int i = 0; i < 3000; i++) { logger.ErrorFormat("test"); } } See the attached VS2005 project for a complete example. One workaround I found is to do the following in the constructor: LogManager.GetRepository().Threshold = Level.Off; This seems a bit strange, because there is no logging visible in either case, yet it runs much slower without that line. Is this expected behaviour?
