after digging deeper it found out that the whole em0 driver worth nothing... when i set the media to auto it's operating in half duplex (i found out after a couple of benchmarks with iperf), when i set it to 100basetx and full duplex manually the result is worse... any idea? ----- Original Message ----- From: "OxY" <oxy@field.hu> To: <freebsd-performance@freebsd.org> Sent: Wednesday, December 28, 2005 9:22 AM Subject: em0 and tunnel performance problem > hi! > > i have an intel etherexpress gigabit card on 100mbit port and fbsd > 6.0-p1.. > my box is a proxy, it's traffic is 100/100mbit constant.. > unfortunately i have to use tunnel and that is the source of my problem. > when i enable the tunnel and the packages are going through it the > performance is poor.. > it seems that it's not full duplex, the speed is around 50/50mbit, and > have 10-15% packet loss.. > i tried to enable/disable polling, and used these sysctl vars: > > kern.polling.enable=1 > kern.ipc.somaxconn=2048 > net.inet.tcp.inflight.enable=0 > net.inet.ip.portrange.randomized=0 > net.inet.tcp.sendspace=65536 > kern.ipc.maxsockbuf=786432 > net.inet.tcp.delayed_ack=0 > net.inet.tcp.newreno=0 > net.inet.ip.intr_queue_maxlen=1024 > net.inet.tcp.blackhole=2 > net.inet.udp.blackhole=1 > net.inet.ip.rtmaxcache=1024 > > without tunnel the speed is 100/100mbit, great. > > ps: with linux its all OK, but i wanna use fbsd :) > > _______________________________________________ > freebsd-performance@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-performance > To unsubscribe, send any mail to > "freebsd-performance-unsubscribe@freebsd.org"
