Parsing large scene is slow. #4
Description
Parsing small scenes works really well.
And, I have this 50k lines, 67mb scene file converted from an .escn file imported from blender. I wanted to shrink its size from the source. I wrote some regex-based scripts and it was neither elegant nor convinent, then I found this parser.
However, It took 11 minutes to parse this 67mb scene. RAM usage increased very slowly and the parsing was using only 6% CPU usage of a Ryzen 2700X.
67mb lines is definitely large, but I think 11 minutes is a bit much. Is it a normal speed with pyparsing or does the script need deeper optimization idk.
