# Base settings and GC logging
-server -XX:+AlwaysPreTouch  # First should be default, but we make it explicit, second pre-zeroes memory mapped pages on JVM startup -- improves runtime performance
# -Xloggc:gc-%t.log  # CUSTOMIZE LOCATION HERE - $path/gc-%t.log -- the %t in the gc log file path is so we get a new file with each JVM restart
-XX:NumberOfGCLogFiles=5 -XX:+UseGCLogFileRotation -XX:GCLogFileSize=20m # Limits the number of files, logs to folder 
-XX:+PrintGC -XX:+PrintGCDateStamps -XX:+PrintGCDetails -XX:+PrintHeapAtGC -XX:+PrintGCCause
-XX:+PrintTenuringDistribution -XX:+PrintReferenceGC -XX:+PrintAdaptiveSizePolicy # gather info on object age & reference GC time for further tuning if needed.

# G1 specific settings -- probably should be default for multi-core systems with >2 GB of heap (below that, default is probably fine)
-XX:+UseG1GC
-XX:+UseStringDeduplication

#  Monkey patch to ActiveRecord to prevent 'implicit' checkouts. Currently tested with Rails 4.0.8, prob
#  should work fine in Rails 4.1 too. 
#
#  If you create a thread yourself, if it uses ActiveRecord objects without
#  explicitly checking out a connection, one will still be checked out implicitly.
#  If it is never checked back in with `ActiveRecord::Base.clear_active_connections!`,
#  then it will be leaked.
