Re: NAPI, rx_no_buffer_count, e1000, r8169 and other actors

Third host r8169 (PCI! This is important, seems i am running out of PCI
capacity), 400Mbit/s rx+tx summary load, e1000e interface also - around

400 rx + 400 tx or 200 rx + 200 tx ?
Can you specify the packet rate and the cpu ?

200Mbps load. What is worrying me - interrupts rate, it seems generated by
realtek card... is there any way to drop it down? 

Also some packetloss, around 0.0005% (i prefer to have clear zero :-)) ). No
nat, no shapers, same kernel configuration.

Can you send an ethtool -S (+ ifconfig) of the 8169 if it misses packets 
as well as the lines of dmesg which relate to the r8169 driver ?
