OK, so do we see that making this change does not affect
performance? This
change uses any String object, not the shared intern() version AND
it uses
String.equals() since it no longer depends on a the single intern()
reference.
And we should test the performance in different JDK's.
The bug report contains benchmarks of the change on JDK 1.4 on Mac,
JDK 1.2 on Win 98SE and JDK 1.5 on Win XP. In all tested platforms,
the change was beneficial both in reducing the time required for the
creation of new loggers by avoiding the String.intern call which
appears to be responsible for approx 30% of the total cost of
creating a new logger and in subsequent retrieval since String.equals
appears (surprisingly) to be faster than ==. I assume that you could
find JDK 1.1 or other implementations where the old code was faster.
