Probably the information is right. A critical point is actually what kind of |
| 13 |
interface you have. Be aware that a gigabit ethernet port has only marginally |
| 14 |
less bandwith than a pci bus (http://www.acme.com/build_a_pc/bandwidth.html). |
| 15 |
If you use the system as a bridge (2 cards) that means that you cannot |
| 16 |
sustain the 1gbs bandwith and will drop packets (even with a single card you |
| 17 |
will, because the pci bus is used for more than the network card). The |
| 18 |
solution would be to use a pci express system. |

ps. dropping packets is not really a problem. (Monitoring dropped packets |
| 23 |
could also be done with ifconfig). |
