Graham, That's not a log4net issue as much as it's an issue in your application. Sounds like your application (like many) makes lots of log.Debug() calls, to log, um, debug information. By switching the logging from DEBUG to INFO you've stopped all those log entries from being written to disk. Even more, if your app developers were smart about it, they checked the IsDebugEnabled property before making the log.Debug() call, so you're not even evaluating the parms to that call, and sometimes that can be quite expensive.
So, it's a "known issue" that logging more stuff takes more time, but I wouldn't call it a bug. -Walden -- Walden H Leverich III Tech Software (516) 627-3800 x3051 [email protected] http://www.TechSoftInc.com Quiquid latine dictum sit altum viditur. (Whatever is said in Latin seems profound.)
