On the LVS, I've got 2:
Ethernet controller: Broadcom Corporation NetXtreme BCM5701 Gigabit Ethernet
(#2) (rev 21).
( working perfectly with 1400 simultaneous users, 2-3 mbits/s traffic on
iptraf )
On the GW, I've got:
2x Ethernet controller: Broadcom Corporation NetXtreme BCM5701 Gigabit
Ethernet (#2) (rev 21).
handling internal traffic to external (public) network with all my 1400
users and 10-12 Mbits/s
4x Ethernet controller: Intel Corp. 82557/8/9 [Ethernet Pro 100] (rev 5)
( in real, those are 2 cards, with 2 NIC on each one ), handling max
100Kbits/s each (management, polling,
and so on ...)
All connections are HTTP requests ...
And my MTU is 1500 on each interfaces ...
But I don't really know how many bytes are answered to any request ...
