    It takes about 40ms on the IBM JVM and around 100ms on the Sun JVM.
    This may not seem like a problem but my computer is quite fast and it
    is desirable to have as many queries as possible (to the external
    device) in a given time. I'm not experiencing data loss unless I try
    and retrieve the data immediately (hence the need to wait for an
    event).

    Thanks in advance for any help,

    George
