Hi, >The negotation is okay, 100baseTX with full-duplex. Or do you mean I >have to force it because it sometimes loses negotiation? Yes, first of all you'll not have error report by netstat -in or by counters on switch Try to force on freebsd and switch the negotiation to 100full if-needed.

Hi, you can look at man 4 re and retrive various informations and BUG. You can see TCP/IP checksum offload and descriptor-based DMA mechanism. You must check if the negotation is OK. (No input error, deferred ...) Es. Force to 100Full. Regards Alessandro __

RE:: 6.x, 4.x ipfw/dummynet pf/altq - network performance issues

Hi, if you disable sack, what's happend? (sysctl net.inet.tcp.sack.enable=0) (Are Memory and cpu OK?) For route problem you can set this to a low value, for example 10 sysctl net.inet.ip.rtexpire: 10 See http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/securing-freebsd.html Why

Hi, I think you can try to check/tuning this sysctl variables and the isr related variables: net.inet.ip.intr_queue_maxlen net.inet.ip.intr_queue_drops net.isr.enable ... try to set net.isr.directed net.isr.queued net.isr.drop and polling configuration: kern.clockrate kern.polling.b

Performance on udp socket

Hi, I've seen a packets drop with high rate of radius authentication request (UDP 150 byte) The software is radiator (perl), and it seems not to be dependent on CPU speed. How is possible to avoid this with a more accurate tuning? #netstat -s -p udp udp: 1917 datagrams received 0 with incom
