Romaric Defaux	Wednesday 27 August 2008 2:59:53 am Hi all ! After installing java/php-java-bridge/lucene on a production box, the server was really really very slowed :( The source of this problem was the java extension in php. In php.ini, when extension=java.so was disabled, the web pages appears instantly. When it was enabled, sometimes we wait many seconds before it appears ! To solve this problem, I changed the default memory for the JVM. In order to do this, I add the following line at the beginning of my /etc/init.d/apache2 file (I don't know if this location is the best way, but it works) : <i> #For java JAVA_OPTS="-Xms256M -Xmx1024M -XX:PermSize=256m -XX:MaxPermSize=256m" export JAVA_OPTS </i> (adapt these parameters to your configuration) And now all works fine :) ! My conf : <i>OS : Gentoo Kernel : linux-2.6.24-gentoo-r4 Ez version : Ez 4.0.0 or 4.0.1 Java version : java version "1.6.0_07" Apache Version : Apache/2.2.8 (Unix) Php version : PHP 5.2.6-pl2-gentoo Lucene version : lucene-2.1.0-r1 Php java bridge version : php-java-bridge-4.3.0</i> I hope this help !

Hi all !

After installing java/php-java-bridge/lucene on a production box, the server was really really very slowed :(

The source of this problem was the java extension in php.
In php.ini, when extension=java.so was disabled, the web pages appears instantly.
When it was enabled, sometimes we wait many seconds before it appears !

To solve this problem, I changed the default memory for the JVM.
In order to do this, I add the following line at the beginning of my /etc/init.d/apache2 file (I don't know if this location is the best way, but it works) :
<i>
#For java
JAVA_OPTS="-Xms256M -Xmx1024M -XX:PermSize=256m -XX:MaxPermSize=256m"
export JAVA_OPTS
</i>

(adapt these parameters to your configuration)

And now all works fine :) !

My conf :
<i>OS : Gentoo
Kernel : linux-2.6.24-gentoo-r4
Ez version : Ez 4.0.0 or 4.0.1
Java version : java version "1.6.0_07"
Apache Version : Apache/2.2.8 (Unix)
Php version : PHP 5.2.6-pl2-gentoo
Lucene version : lucene-2.1.0-r1
Php java bridge version : php-java-bridge-4.3.0</i>

I hope this help !

Regards

Romaric
