LVS-NAT, Min 30Mbps, Max 78 Mbps output with P3@1000 Mhz quad tulip-based
FastEthernet card. Average packet size = 800 bytes. Works for three months
(we could reach 150 Mbps with SMP machine/kernel and bonding driver)
Same setup but for a smaller cluster (max 40Mbps, min 12 Mbps) works for 6
months.
Balanced traffic: HTTP (85%) and FTP (15%)
The only problem are the real servers, that have to grow in number :)
