I tried to improve my Wikipedia Miner instance but the Waikato University demo is twice as fast as mine.
I tried following configuration:
- 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
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:
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!,
