Lost packets and dead/warntime

[Michael Gale]

Hello,

	What nics are you using ?

Packet loss can some times be traced down to the type of network cards 
you are using. Server class network cards usually have larger buffers 
and therefor can handle more traffic.

Are you using a server class card or a desktop adapter ?
