I think UUID.randomUUID().toString() has some performance bottle necks even
though its negligible, as it internally uses SecureRandom API which is a
synchronized method.
if possible explore more on this as our system is more performance driven.
What about using JUG?
There is also a time bound uuid generation which seems to work lot faster
compare to normal UUID generation supported by java.
Following link will give you a fair idea regarding implementation and
performance comparison.
