+# HEAP SETTINGS #
+#################
+
+# Heap size is automatically calculated by cassandra-env based on this
+# formula: max(min(1/2 ram, 1024MB), min(1/4 ram, 8GB))
+# That is:
+# - calculate 1/2 ram and cap to 1024MB
+# - calculate 1/4 ram and cap to 8192MB
+# - pick the max
+#
+# For production use you may wish to adjust this for your environment.
+# If that's the case, uncomment the -Xmx and Xms options below to override the
+# automatic calculation of JVM heap memory.
+#
+# It is recommended to set min (-Xms) and max (-Xmx) heap sizes to
+# the same value to avoid stop-the-world GC pauses during resize, and
+# so that we can lock the heap in memory on startup to prevent any
+# of it from being swapped out.
+#-Xms4G
+#-Xmx4G
+
+# Young generation size is automatically calculated by cassandra-env
+# based on this formula: min(100 * num_cores, 1/4 * heap size)
+#
+# The main trade-off for the young generation is that the larger it
+# is, the longer GC pause times will be. The shorter it is, the more
+# expensive GC will be (usually).
+#
+# It is not recommended to set the young generation size if using the
+# G1 GC, since that will override the target pause-time goal.
+# More info: http://www.oracle.com/technetwork/articles/java/g1gc-1984535.html
+#
+# The example below assumes a modern 8-core+ machine for decent
+# times. If in doubt, and if you do not particularly want to tweak, go
+# 100 MB per physical CPU core.
