    Hi all,

    I tried to improve my Wikipedia Miner instance but the Waikato University demo is twice as fast as mine.

    I tried following configuration:

    Hardware:
    - Amazon m2.2xlarge instance:
    34.2 GB of memory
    13 EC2 Compute Units (4 virtual cores with 3.25 EC2 Compute Units each)
    850 GB of instance storage
    64-bit platform
    I/O Performance: High

    - Tomcat 7 with Java 7:
    JAVA_OPTS = "-Xms8g -Xmx34g -XX:+UseAdaptiveSizePolicy -XX:+AggressiveHeap"
    CATALINA_OPTS = "-Xms8g -Xmx34g -XX:+UseAdaptiveSizePolicy -XX:+AggressiveHeap"

    - Wikipedia Miner:
    In configuration file named wikipedia.xml:

            <databaseToCache priority="speed">pageLinksIn</databaseToCache>
            <databaseToCache priority="speed">label</databaseToCache>

    To cache frequently used files in the database

    And nothing else.

    I do not know what else I can do to improve performance. I need better performance. This is critical in my project.

    Any ideas? Does anyone know a better setup?

    Help me, please!

    Thanks you in advance!,
