You should be 20x (or more) at 1GbE. Something isn't right. Are you getting any other Rx errors? It sounds like you're having trouble getting packets out of the Rx FIFO and DMA'ed across the bus into host buffers. We need to know if the FIFO is gummed up because we're receiving faster than we can DMA out of the FIFO, we're not getting Rx buffers (unlikely), or the hardware descriptor ring is full and we're being throttle by the polling rate of NAPI (also unlikely at this rate). The Rx errors should tell us where the bottleneck is. What's that other device doing? -scott - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
