607# The detection engine builds internal groups of signatures. The engine
608# allow us to specify the profile to use for them, to manage memory on an
609# efficient way keeping a good performance. For the profile keyword you
610# can use the words "low", "medium", "high" or "custom". If you use custom
611# make sure to define the values at "- custom-values" as your convenience.
612# Usually you would prefer medium/high/low.
613#
614# "sgh mpm-context", indicates how the staging should allot mpm contexts for
615# the signature groups. "single" indicates the use of a single context for
616# all the signature group heads. "full" indicates a mpm-context for each
617# group head. "auto" lets the engine decide the distribution of contexts
618# based on the information the engine gathers on the patterns from each
619# group head.
620#
621# The option inspection-recursion-limit is used to limit the recursive calls
622# in the content inspection code. For certain payload-sig combinations, we
623# might end up taking too much time in the content inspection code.
624# If the argument specified is 0, the engine uses an internally defined
625# default limit. On not specifying a value, we use no limits on the recursion.
