Summary0033646: Coding - Performance analyzing of OCCT RTTI
DescriptionOCCT RTTI looks like have an additional resource for mutex and real-time loading and processing.
Especially OCCT RTTI impact on multithreading processing.
Need to analyze impact and in non-relevant result replace OCCT RTTI by Dynamic cast and std::type_info operations.
TagsNo tags attached.

    0033646: Coding - Performance analyzing of OCCT RTTI
    
    First iteration of testing.
      There are 2 options: continue to use type_info or going to pure downcast functionality
    
    Current solution - reorganize Standard_Type to be as a type_info temp object.
    There are limitation based on extraction parents classes, but can be develop for specific usages with new method for only some objects.
    
    Later need to replace "Handle(Standard_Type)&" with "Handle(Standard_Type)". There are no more references.

    // new test solution to test pure down-cast functionality.
    
    Another solution will be store instances without maps and mutexes (recursive list)

    middle solution - no improvements
      needs to create a static instances with type_info only
    the goal - avoid mutex and internal cache map (it is already part of STD)

There are no difference for Memory or CPU, but at least there are no regressions at that parameters.
The solution is possible. The benefit is avoid global map of types.
