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)

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

One Peer Receive Only

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

	v6.44	v7.1beta3	v7.15.3 (1008427 routes)	v7.16 (1008427 routes)

CCR2116			0:36	0:34
CCR2216			0:39	0:34
CCR2216 (150 regexp as-path rules)				2:09

Two Peers Receive Only

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

	v6.44	FRR	v7.1beta3	v7.1rc7 (846k routes per peer)
CCR	1:01 - 2:45		1:11
RB1100x4 1.4GHz	0:51		0:30
CCR2004	0:51		0:29	0:33
router x				0:40
x86 (CHR)	0:25
x86 (virtual)		0:26(4cores)
		0:46(2cores)
		0:30(2cores no LDP)

Multi-homing Sim

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