log4net vs Enterprise Library, which is better? faster?

Question

Anyone know of some performance comparisons of the latest version Enterprise Library and the latest version of log4net?

Any technical reason why I should choose one over the other?

Answer 1

Having used both, I recommend the Enterprise Library for large projects where ease of configuration has higher priority over performance and size.

For everything else, I'd use log4net.

Answer 2

Log4Net is faster for one - not to mention that you can buffer your log INSERTs. For the logs I don't need to be real-time up to date, I set a buffer of 10k messages.

Log4Net also has more ways to consume the log data - db appenders, event log, rolling file, email, etc, etc.

Answer 3

I would go for log4net

Answer 4

I'm asking myself the same question right now, and in looking at the docs for EntLib's logging, i see that it requires references to the following asssemblies (5):
--Microsoft.Practices.Unity.dll
--Microsoft.Practices.Unity.Interception.dll
--Microsoft.Practices.ServiceLocation.dll
--Microsoft.Practices.EnterpriseLibrary.Common.dll
--Microsoft.Practices.EnterpriseLibrary.Logging.dll

On the other hand, log4net requires these assembly references (1):
--log4net.dll

So at least on first glance, log4net is much more lightweight.
