   1 IPSec Crypto HW: IP4 Routed-Forwarding
   2 ======================================
   3
   4 This section includes summary graphs of VPP Phy-to-Phy packet latency
   5 with IPSec encryption used in combination with IPv4 routed-forwarding,
   6 with latency measured at 50% of discovered NDR throughput rate. VPP
   7 IPSec encryption is accelerated using DPDK cryptodev library driving
   8 Intel Quick Assist (QAT) crypto PCIe hardware cards. Latency is reported
   9 for VPP running in multiple configurations of VPP worker thread(s),
  10 a.k.a. VPP data plane thread(s), and their physical CPU core(s)
  11 placement.

  13 VPP packet latency in 1t1c setup (1thread, 1core) is presented in the graph
  14 below.
