Quotes row read the same file with added quotes around the cell. Parallel uses the ParallelReader to load read and decode the file in a separate thread. Concurrent use the concurrent reading of univocity. The percentage is the cost difference compare to the same sfm configuration (quotes/noquotes, singlethreaded/parallel)
