Expanding Alfresco JVM memory

When we launch for first time Alfresco Comunity 3.2, we get this warning:

Alfresco JVM - WARNING - maximum heap size 494.938MB is less than recommended 512MB

We have to expand the JVM memory to solve it. Go to Alfresco install home and edit the alfresco.bat/alfresco.sh file , and modify the JAVA_OPTS like that:

Linux:
export JAVA_OPTS='-Xms256m -Xmx1024m -XX:MaxPermSize=512m -server

  
Windows:
set JAVA_OPTS='-Xms256m -Xmx1024m -XX:MaxPermSize=512m -server
