Currently, the company was able to give me only a Windows server 2003 R2 32bit, so I could give him only the following parameters in the service of windows :

-Xms1024M
-Xmx1024M
-Dalfresco.home=C:\Alfresco
-Dcom.sun.management.jmxremote
-Dcatalina.base=C:\Alfresco\tomcat
-Dcatalina.home=C:\Alfresco\tomcat
-Djava.endorsed.dirs=C:\Alfresco\tomcat\endorsed
-XX:MaxPermSize=256m
-Djava.io.tmpdir=C:\Alfresco\tomcat\temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=C:\Alfresco\tomcat\conf\logging.properties
-XX:+UseConcMarkSweepGC
-XX:+CMSIncrementalMode
-XX:CMSInitiatingOccupancyFraction=70

I use Lucene indexes with the configurations :
dir.indexes=f:/Alfresco/alf_data/lucene-indexes
dir.indexes.backup=f:/Alfresco/alf_data/backup-lucene-indexes
index.subsystem.name=lucene
index.recovery.mode=AUTO
