Hi Maybe my problem is litle offtopic to this list , but maybe someone had something similar like this , and have some good solution . Ok, I've have router with four intel e1000 pci-x(2x100Mhz/2x133Mhz) nics that push about 200Mbit/s , and I'm using nload for realtime traffic monitoring. Everything was great until I've updated kernel to 2.6.17.13 . After update nload is showing some crazy values . I've tried to get counters from /proc/net/dev (like nload). root@kaermorhen:~# while true; do cat /proc/net/dev|grep eth0; sleep 1; done eth0:1013729758 572932250 0 1882102 0 0 0 0 1572910106 3860638290 0 0 0 0 0 0 eth0:1055515817 573004372 0 1882102 0 0 0 0 1601291109 3860694606 0 0 0 0 0 0 eth0:1055515817 573004372 0 1882102 0 0 0 0 1601291109 3860694606 0 0 0 0 0 0 eth0:1097729573 573076432 0 1882102 0 0 0 0 1629536436 3860751311 0 0 0 0 0 0 eth0:1097729573 573076432 0 1882102 0 0 0 0 1629536436 3860751311 0 0 0 0 0 0 eth0:1139487258 573148469 0 1882102 0 0 0 0 1658034498 3860807633 0 0 0 0 0 0 eth0:1139487258 573148469 0 1882102 0 0 0 0 1658034498 3860807633 0 0 0 0 0 0 eth0:1181148113 573220076 0 1882102 0 0 0 0 1685931047 3860863738 0 0 0 0 0 0 Between second and third second counter increase of 0 bytes, 1055515817-1055515817=0 the same for fourth and fifth ( on mrtg graphs I've about 140Mbit/s incoming traffic - 17.5 MB/s ). On other router I've kernel 2.6.14.7 , e1000/2xe100 32bit nics , and interfece counters in /proc/net/dev are looking good: eth0:2101453114 3324697664 3604 3441 3441 92 0 1347064 867323793 3458783738 0 0 0 0 0 0 eth0:2107451373 3324705778 3604 3441 3441 92 0 1347066 874688831 3458792480 0 0 0 0 0 0 eth0:2113352907 3324713495 3604 3441 3441 92 0 1347066 881546913 3458800862 0 0 0 0 0 0 eth0:2119707847 3324721929 3604 3441 3441 92 0 1347069 889060588 3458809975 0 0 0 0 0 0 eth0:2125601276 3324729816 3604 3441 3441 92 0 1347070 896165072 3458818569 0 0 0 0 0 0 2113352907-2107451373=5901534 (traffic on intefece about 40Mbit/s = 5MB/s) - seems good. Both routers have CONFIG_HZ=1000, two cpus, and bofh are using e1000/e100 driver with enabled NAPI. Besides I've similar thing on laptop, 2.6.14 , Broadcom BCM4401-B0 nic (b44) :) Why interface counters are increasing so slowy? this behavior can be changed? or in other way this is normal behavior or some bug , feature? /pch -- Dyslexia bug unpatched since 1977 ... exploit has been leaked to the underground. _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
