+# - SoftRefLRUPolicyMSPerMB would default to 1000 which with a 4gb heap translates to ~51 minutes.
+#   A value of 1 means ~4 seconds before SoftRefs can be collected, which means its realistic to
+#   collect them as needed during a build that should take seconds to minutes.
+# - CodeCache normally defaults to a very small size. Increasing it from platform defaults of 32-48m
+#   because of how many classes can be loaded into memory and then cached as native compiled code
+#   for a small speed boost.
