3 Performance Summary
This section summarizes the performance of the 4450 Security Processor functional units.
For complete details about performance differences between algorithms and modes on the
4450 with the latest SDK firmware, please see 4450/8450 Performance Application Note,
AN-0168. The 4450/8450 Product Release Note, RN-0118, for the SDK may also provide
additional performance information.
The performance data reflects the following conditions:
• 200 MHz operating frequency
• Packets across single or multiple security associations
• Encoded text throughput
