+## Performance tuning and profiling
+##
+
+# The detection engine builds internal groups of signatures. The engine
+# allows us to specify the profile to use for them, to manage memory in an
+# efficient way keeping good performance. For the profile keyword you
+# can use the words "low", "medium", "high" or "custom". If you use custom,
+# make sure to define the values in the "custom-values" section.
+# Usually you would prefer medium/high/low.
+#
+# "sgh mpm-context", indicates how the staging should allot mpm contexts for
+# the signature groups. "single" indicates the use of a single context for
+# all the signature group heads. "full" indicates a mpm-context for each
+# group head. "auto" lets the engine decide the distribution of contexts
+# based on the information the engine gathers on the patterns from each
+# group head.
+#
+# The option inspection-recursion-limit is used to limit the recursive calls
+# in the content inspection code. For certain payload-sig combinations, we
+# might end up taking too much time in the content inspection code.
+# If the argument specified is 0, the engine uses an internally defined
+# default limit. When a value is not specified, there are no limits on the recursion.

+## Netfilter integration

+
+# When running in NFQ inline mode, it is possible to use a simulated
+# non-terminal NFQUEUE verdict.
+# This permits sending all needed packet to Suricata via this rule:
+# iptables -I FORWARD -m mark ! --mark $MARK/$MASK -j NFQUEUE
+# And below, you can have your standard filtering ruleset. To activate
+# this mode, you need to set mode to 'repeat'
+# If you want a packet to be sent to another queue after an ACCEPT decision
+# set the mode to 'route' and set next-queue value.
+# On Linux >= 3.1, you can set batchcount to a value > 1 to improve performance
+# by processing several packets before sending a verdict (worker runmode only).
+# On Linux >= 3.6, you can set the fail-open option to yes to have the kernel
+# accept the packet if Suricata is not able to keep pace.
+# bypass mark and mask can be used to implement NFQ bypass. If bypass mark is
+# set then the NFQ bypass is activated. Suricata will set the bypass mark/mask
+# on packet of a flow that need to be bypassed. The Nefilter ruleset has to
