We use this chip (actually, the entire family) on many of our products (PPC, x86, and MIPS). Our data indicates that the chip can sustain wire-saturation with minimum size packets. However, many CPUs cannot keep up with the load created by interrupts coming in at that rate. There are probably some driver enhancements (interrupt combining, etc.) which could be made to improve the situation. But it's not a silicon problem. Matt -- Matthew D.
