Re: [logback-user] Elongated system startup-time because of Logback configuration

On my machine it takes 900 milliseconds to parse and run your configfile. It takes about 500 millis to parse and empty config file. So while900 millis is not particularly fast, it's still much faster than the 45seconds you report. Is it possible that the config file is located onthe network (and the network suffers from DNS timeouts)?

Yes there is improvement in start-up time, if there is no logging using logabck
in my system.


Loggers don't require their own thread and don't create one. 25 loggers

shouldn't be a big deal.

Can you send you logback.xml?
