Answer 1

In Jmeter version 3.x it is mentioned in $JMETER_HOME/bin/jemter.sh(jmeter.bat):

## Environment variables:
## JVM_ARGS - optional java args, e.g. -Dprop=val
## e.g.
## JVM_ARGS="-Xms512m -Xmx512m" jmeter.sh etc.

so in your case you can set it as much as sufficient to your needs for example:

JVM_ARGS="-Xms1024m -Xmx1024m"
