EIGRP Unequal Cost Load Balancing

Hi GS,
I have doubts regarding EIGRP Unequal Cost Load Balancing.

I have a questions:

1. If we have CEF enabled on both interfaces and just add variance 2 command
under EIGRP, then for example we achived traffic share count like 2:1, but
how really traffic is sending to the remote devices. With CEF on interface
and variance we have per-destination sharing load sharing.
Does it mean that for examle if we have just one route that appears in the
routing table with 2:1 ratio and we ping from our router (always with the
same source IP to the same destination) then we really dont achived any load
balancing because CEF sends the packets based on the created flow (src and
dest IP, so always the same).
So what exactly this variance + CEF do for us? Does it mean that to take
adavantage from the variance we have to disable CEF?

2. If we add ip load-sharing per-packet command under interface then we
have per-packet sharing under show ip cef X.X.X.X, does it mean that thanks
to this command we disabled CEF on this interfaces and we have packets that
are process switched.

Thanks for clarigfications
