    3737This overhead has little impact on the overall performance of these parsers
    3838as they experience additional overheads related to branch mispredictions.

     39When compared with Xerces and Expat, the data organization of Parabix-XML

    6565Note that, in each workload, the number of non-SIMD instructions
    66 remains relatively constant with each workload.  As expected,
     66remains relatively constant with each implementation.  As expected,
    6767the number of bitwise SIMD operations remains the same
    6868for both SSE and 128-bit AVX while dropping dramatically when operating
