    22\subsection{Performance}
    3 Figure \ref{Scalability} shows the performance of Parabix2 on three different cores: core2, corei3 and sandybridge.
    4 The processing time, which is evaluated as CPU cycles per thousand bytes,
     3Figure \ref{Scalability} (a) shows the performance of Parabix2 on three different cores: core2, corei3 and sandybridge.
     4The average processing time of the five workloads, which is evaluated as CPU cycles per thousand bytes,
    55is divided up by bitstream parsing and byte space postprocessing.
    66Bitstream parsing, mainly consists of SIMD instructions,
     
    11110 to 17\% performance improvement moving from corei3 to sandybridge.

    13 As comparison, we also measured the performance of Expat on all the three cores.
     13As comparison, we also measured the performance of Expat on all the three cores, which is shown is Figure \ref{Scalability} (b).
    1414The performance improvement is less than 5\% by running Expat on corei3 instead of core2
    1515and it is less than 10\% by running on sandybridge instead of corei3.
