Excuse all. I should have double checked my results...
The javadoc should nevertheless IMHO be updated so as to reflect the
current difference between Vector and Chain. (i.e. 3 times slower instead
of 20)

Hi all,
I made some tests in org.apache.log4j.performance.ListVsVector.
(Whose purpose is "Compares the performance of looping through a list
versus a Vector.")
You said there that "Chain looping is *20* times faster than vector
access on JDK 1.1.7B on NT".
I made the same test with jdk1.4.1_01 on
