The default heap size is 512m. This is hardcoded in the bin/solr script. You can override that with the -m parameter. If you are not using the bin/solr script and are instead doing the old "java -jar start.jar" startup, the default heap size is determined by the version of Java you are running. Thanks, Shawn
