      Description

        java.net.InetAddress caches results from name service lookups to improve performance and minimize load on name services. The caching mechanism was designed before java.util.concurrent existed and is using locking algorithms. This scales poorly with multithreaded hardware. Tools exist today that can improve multithreaded scalability of InetAddress cache.
