Hi,

>From the log4j sources:
public
boolean isDebugEnabled() {
if(hierarchy.disable >= Priority.DEBUG_INT)
return false;
return Priority.DEBUG.isGreaterOrEqual(this.getChainedPriority());
}
The getChainedPriority is a recursive method:
for(Category c = this; c != null; c=c.parent)
{
if(c.priority != null)
return c.priority;
}
Save the result in a boolean and test the boolean will improve performance.
I am not at all a performance guru, I have no idea at which level it will.
It is a good idea to do what you propose.
