Performance Status

Used hardware:

CCR1036, 16GB RAM (tile)
CCR2004(arm64)
CCR1100AHx4(arm)
Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz 32GB RAM (as a host for CHRs)

Simulated upstream peer is CHR router running ROSv6 with copy of global IPv4 routing table (585K routes loaded from MRT dump).

One Peer Receive Only

DUT establishes connection to simulated upstream peer, receives routes and installs them in FIB.

CCR	0:40 - 2:12	0:46
RB1100x4 1.4GHz	0:32-0:38	0:23
CCR2004	0:32	0:18
x86 (CHR)	0:20

RB450G affinity main	-	1:54
RB450G affinity in=alone out=in	-	2:12

Two Peers Receive Only

DUT establishes connection to two simulated upstream peers, receives routes, picks best route and installs in FIB. On ROSv7 affinity settings set to "alone".

	v6.44	FRR	v7.1beta3
CCR	1:01 - 2:45		1:11
RB1100x4 1.4GHz	0:51		0:30
CCR2004	0:51		0:29
x86 (CHR)	0:25
x86 (virtual)		0:26(4cores)
		0:46(2cores)
		0:30(2cores no LDP)

Multi-homing Sim

Two DUT devices establishes eBGP sessions to simulated x86 upstream router. Both DUTs are interconnected with iBGP session. Each DUT receives routes from upstream and readvertise routes over iBGP. On ROSv7 affinity settings set to "alone" and early-cut disabled.
