        Description

        Applet startup time under IE increased significantly with 8u60. It is
        approximately 10-20 times slower with 8u60 compared to 8u51.

        With the attached testcase we see the following results:

        IE 11 - Java 8u60
        - First time: around 28 seconds
        - 2nd time: around 20 to 25 seconds
        - After browser restart: 25 to 28 seconds

        IE 11 - Java 8u51
        - First time: around 5-8 seconds
        - 2nd time: 1 second
        - After browser restart: around 5-8 seconds

        The problem is not reproducible with Firefox.

        There are a few existing bugs which appear to report similar behavior.
        JDK-8134741 seems to describe a similar issue. 8134741 was closed as
        a duplicate of 8134469. 8134469 appears to be specific to situations in
        which multiple applets are loaded concurrently, unlike the situation
        presented here. 8134469 was closed as a duplicate of 8133665. A fix for
        8133665 was integrated into 8u65-b14, but we tested that build also exhibits
        the same startup time regression.
