 It has been a long time since I last used Haiku but I recently started
 using it again. I noticed there has been a huge network performance
 regression (more likelly, with my specific card as someone else would
 have noticed it if the problem was more general).

 Here is my card:

        Hardware type: Ethernet, Address: 00:1e:8c:3a:65:24
        Media type: 1 GBit, 1000BASE-T
        inet addr:, Bcast:, Mask:
        inet6 addr: fe80::21e:8cff:fe3a:6524, Bcast:
 ffff:ffff:ffff:ffff::, Prefix Length: 64
        MTU: 1500, Metric: 0, up broadcast link auto-configured
        Receive: 5880 packets, 0 errors, 4661150 bytes, 0 mcasts, 0 dropped
        Transmit: 2737 packets, 0 errors, 253011 bytes, 0 mcasts, 0 dropped
        Collisions: 0

 As you can see it is connected to a Gigabit ethernet network and the
 speed is not getting even close to that. And when I say not even close
 I do not say I am getting 10 Mbits or something. I am getting amazing
 425 Kbits! or 52 kb/s in the local network. The same machine also runs
 Linux and when booted to it, I get around 40 mb/s of transfer speed.

 Also, ping times are surreal:

 [/boot/home]> ping
 PING ( 56 data bytes
 64 bytes from icmp_seq=0 ttl=64 time=333.856 ms
 64 bytes from icmp_seq=1 ttl=64 time=334.960 ms
 64 bytes from icmp_seq=2 ttl=64 time=336.313 ms
 64 bytes from icmp_seq=3 ttl=64 time=337.703 ms
 64 bytes from icmp_seq=4 ttl=64 time=339.046 ms
 64 bytes from icmp_seq=5 ttl=64 time=340.501 ms
 64 bytes from icmp_seq=6 ttl=64 time=341.911 ms
 64 bytes from icmp_seq=7 ttl=64 time=343.321 ms
 64 bytes from icmp_seq=8 ttl=64 time=344.734 ms
 64 bytes from icmp_seq=9 ttl=64 time=346.066 ms
 64 bytes from icmp_seq=10 ttl=64 time=347.479 ms
 --- ping statistics ---
 11 packets transmitted, 11 packets received, 0% packet loss
 round-trip min/avg/max/std-dev = 333.856/340.535/347.479/4846.743 ms

 On Linux on the same machine, the same ping results in sub-ms reply time,
 so this is aroung 500 times slower!

 Also notice this card use the FreeBSD compatibility layer. It is possible
 that the problem is there.
