24 ports of e1000 nics means 24 interrupts used (or shared). Maybe

Hi All,
I have a box with 24 e1000 cards in it. They are configured as 12
bridges, each with 2 ports.
I have found that when the total traffic on the box gets to around
100Mbps or so, it starts dropping packets.
As far as I can tell, it's related to the amount of traffic per card,

11 matches
