HP-UX IPSec vA.02.00 Performance and Sizing White Paper

Comparative Results
Figure 11 shows that HP-UX IPSec throughput scales well. When using a 32768-byte send buffer,
throughput for a two-way, dual NIC card configuration is approximately double the throughput for a
one-way, single NIC card configuration.
Figure 11. One-Way and Two-Way, 2 NICs Throughput for ESP-AES
Figure 12 shows that HP-UX IPSec service demand (the CPU time req
uired to send one kilobyte of
data, in microseconds; lower is better) scales well. Service demand for a two-way, dual NIC card
configuration is nearly the same as the service demand for a one-way, single NIC card configuration
