In general, the maximum total throughput for the QSIM/HSIM/FAM is 31250
packets per second (pps). This is for full duplex traffic. Cases involving small size
frames requires high processing capacity when compared to that of large size
frames. With small size frames, test results show the PPS performance listed in the
following tables. Note that the maximum PPS is 31250.
