[logback-user] logback console appender slow on windows xp

[ceki]

Thank you for the output of visualvm profiler. It looks like 90.4% of 
the time is spent in java.io.PrintStream.write(int) called by 
ch.qos.logback.core.joran.spi.ConsoleTarget. There is also some time 
spent in java.io.IOException.<init>(String), i.e the constructor of 
IOException.

In principle, the performance of log4j ConsoleAppender should be very 
similar, although its execution path might be slightly shorter.

Which version of log4j are you using?
