Hi list, A few days ago I tested whether a FreeBSD 7 box is able to handle Gigabit traffic. So I used a Cisco 7600 and added static routes from the router to the box and from the box to the router, so that some packets would loop between the two. Then I externally injected 30Mbps of "ping -f -t 255 -s <size>", which should have generated a "maximum" of 3,6Gbps. I then used nload on the box to graph the bandwidth.
The box is a Intel Core 2 Duo, with a PCIe re NIC. I used FreeBSD i386 with polling and fastforwarding. No WITNESS, INVARIANTS or firewalls. I was amased to see that injecting 1000 bytes packets gave a maximum throughput of 650Mbps, while 1400 bytes gave 750Mbps. During both tests one core was 98% idle, while the other one was more than 80% idle. Can anybody point me what the bottleneck of this configuration is? CPU was mostly idle and PCIe 1x should carry way more. Or is the experiment perhaps fundamentally flawed? Thanks. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
