Find the command that you use to start the server that runs Solr (Tomcat or Jetty) and add java heap size options to it - e.g. -Xmx500m will set a max heap size of 500 MB, and -Xms300m will set an initial heap size of 300 MB.

For Tomcat, find catalina.sh, open it up and find the line that sets CATALINA_OPTS. Add the options for -Xms and -Xmx to that line. In Windows you don't put them in quotes, and in Linux you do.
