Performance Measurements of Linux, DanOS, VYOS, VPP, and Linux XDP at 100GE

Tests still being performed - check back at the end of March 2022 for final results

Results:

Table below represent Millions of Packets Per Second (MPPS) send for forwarding via the router software vs packetloss of the end destination of expected packets.
Note:
- droptest % represents the % of loss of the legitimate packets
- some higher rates not tested once significant loss was demonstrated at lower levels
- no optimisations performed on these routers unless otherwise noted below

Test Environment & pktgen tool

Network Card:

mlx5_core 0000:3b:00.1: firmware version: 16.27.6120
mlx5_core 0000:3b:00.1: 126.016 Gb/s available PCIe bandwidth, limited by 8.0 GT/s PCIe x16 link at 0000:3a:00.0 (capable of 252.048 Gb/s with 16.0 GT/s PCIe x16 link)

We wont go into building pktgen as there's plenty of doco out there on this.  Just for reference purposes on how we ran pktgen:

LD_LIBRARY_PATH=/usr/local/lib64/ /root/pktgen-dpdk/usr/local/bin/pktgen -l 2,4,6 -n 2 -a 3b:00.1 -d librte_net_mlx5.so  -- -p 0x1 -P -m "[4:6].0"

Traffic generated:
Static destination MAC (The test Target)
pktgen:

set 0 rate 10   (This is % of 100GE, adjusted accordingly at 1% = 1.5MPPS)
set 0 size 64
set 0 count 50000000
set 0 proto udp
set 0 dst ip 10.22.23.102
set 0 src ip 10.22.22.101/24
set 0 dst mac XX:XX:XX:XX:d1:7b
set 0 src mac XX:XX:XX:XX:36:75
set 0 type ipv4

Single flow:
Single target IP address
UDP traffic, 64 bytes per packet, same src/dst ports
No firewall policies

Single flow, 5 firewall policies:
Single target IP address
UDP traffic, 64 bytes per packet, same src/dst ports
5 firewall policies

Single flow, 50 firewall policies:
Single target IP address

50 firewall policies

Single flow, GRE tunnel:
Single target IP address
UDP traffic, 64 bytes per packet, same src/dst ports
50 firewall policies
GRE encap traffic and forward to static destination

Multiple flow:
254 destination IP addresses (multi-flow)
UDP traffic, 64 bytes per packet, random src ports (multi-flow)
50 firewall policies
pktgen:

900K Route Test:
254 destination IP addresses
UDP traffic, 64 bytes per packet, random src/dst ports
50 firewall policies
900K loaded route table

Drop Test:
1  destination IP addresses, multiple ports (multi-flow)
UDP traffic, 64 bytes per packet, random src/dst ports
50 firewall policies, default deny
900K loaded route table
Half test traffic configured to be dropped
