QSIM/HSIM/FAM Performance at Small Frame Sizes
Note that this section pertains to QSIM, HSIM, and FAM performance with traffic
running at small frame sizes. Table 37, Table 38, and Table 39 describe the
configurations supported when the QSIM, HSIM, and FAM, respectively, are
running at small frame sizes.
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.
