Felipe Zimmerle	a8ba54e1ab	Cosmetics: Using VariableValues instead of std::vector<...> ... Making the code more readable.	2020-11-16 10:01:42 -03:00
WGH	1b13e041ce	Use std::shared_ptr for variable resolution ... AnchoredSetVariable::resolve is called for every rule (see RuleWithOperator::evaluate). The previous implementation allocated a new copy of every variable, which quickly added up. In my tests, AnchoredSetVariable::resolve function consumed 7.8% of run time. AnchoredSetVariable (which is a multimap) values are never changed, only added. This means it's safe to store them in std::shared_ptr, and make resolve return shared_ptr pointing to the same object. Other resolve implementation could also use this optimization by not allocating new objects, however, they are not hot spots, so this optimization was not implemented there. In my benchmark, this raises performance from 117 requests per second to 131 RPS, and overhead is lowered from 7.8% to 2.4%. As a bonus, replacing plain pointer with smart pointers make code cleaner, since using smart pointers makes manual deletes no longer necessary. Additionally, VariableOrigin is now stored in plain std::vector, since it's wasteful to store structure containing just two integer values using std::list<std::unique_ptr<T>>.	2020-11-16 10:01:42 -03:00
