Description (partial)


For 64-byte packets, maximum packet rate achievable on a SAMI running 12.2(33)SRD version of the 
IOS software is only 640,000 packets per second. This is approximately 20% lesser compared to the 
maximum achievable packet rate of 800,000 packets per seconds on a SAMI  running 12.4 version of 
IOS for same sized packets.


The degradation in packet rate is observed with plain CEF switched packets without any extra 
features configured.
