To adjust the heap memory size in these versions, simply change the SOLR_HEAP environment variable. For additional Java tuning, see the solr.in.sh script in vufind/solr/vendor/bin/.
 If you are using the included distribution of Jetty, the tuning options are set in the JAVA_OPTIONS environmental variable. You can either set this for the user running the instance of Jetty (recommended) or in /etc/profile.
