I have a sheevaplug How much can a guruplug perform using 2 nics ? We do have some gaming people and people using voip/sip. Any idee on howto generate traffic and measure different quality aspect like latency ? /Per ------------------------------------------------------------------------------ Increase Visibility of Your 3D Game App & Earn a Chance To Win $500!
