     Since Parser 3.4.0 the several optimisations were implemented.
     If you experience problems you can try to disable them by commenting corresponding defines and recompiling parser3.

       #define USE_DESTRUCTORS    -- destructors are used to decrease memory consumption during code
                                     processing and make ^memory:compact[] calls non-essential.
   
     src/types/pa_method.h
       #define OPTIMIZE_CALL      -- allows faster operators execution by eliminating method frame
                                     with local variables creation and extra write context switches.
       #define OPTIMIZE_RESULT    -- parser methods are marked when the $result variable was used.
                                     This allows write operations and context switching optimization.
   
     src/types/pa_wwrapper.h
       #define OPTIMIZE_SINGLE_STRING_WRITE  -- reuse original VString in single string assignments.
   
     src/lib/cord/include/cord.h
       #define CORD_CAT_OPTIMIZATION -- CORD library never modifies source concatenations. But in parser
                                        write operations it is safe to modify them and save some memory.

       #define STRING_LENGTH_CACHING -- cache String::Body.length() for char* strings
