Switches like this and the force10 2410 and the like are cut through so do sub micro second versus a 'regular' store and forward switch

Arista claims to have the fastest 1/10 Gig 24 and 48 port 1RU switch,
with a backplane capacity guaranteeing 10 Gig full duplex line rate per

Cisco's CEF is local only and functions to download the arp cache and
routing table into ASICs for hardware switching; but look at Cisco's
NSF/SSO for cases where adjacent devices are all defined in the same
packet forwarding state machine.
