Very low network performance on some Marvell Yukon cards.
|Reported by:||bga||Owned by:||nobody|
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:
/dev/net/marvell_yukon/0 Hardware type: Ethernet, Address: 00:1e:8c:3a:65:24 Media type: 1 GBit, 1000BASE-T inet addr: 192.168.0.11, Bcast: 192.168.0.255, Mask: 255.255.255.0 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 192.168.0.1 PING 192.168.0.1 (192.168.0.1): 56 data bytes 64 bytes from 192.168.0.1: icmp_seq=0 ttl=64 time=333.856 ms 64 bytes from 192.168.0.1: icmp_seq=1 ttl=64 time=334.960 ms 64 bytes from 192.168.0.1: icmp_seq=2 ttl=64 time=336.313 ms 64 bytes from 192.168.0.1: icmp_seq=3 ttl=64 time=337.703 ms 64 bytes from 192.168.0.1: icmp_seq=4 ttl=64 time=339.046 ms 64 bytes from 192.168.0.1: icmp_seq=5 ttl=64 time=340.501 ms 64 bytes from 192.168.0.1: icmp_seq=6 ttl=64 time=341.911 ms 64 bytes from 192.168.0.1: icmp_seq=7 ttl=64 time=343.321 ms 64 bytes from 192.168.0.1: icmp_seq=8 ttl=64 time=344.734 ms 64 bytes from 192.168.0.1: icmp_seq=9 ttl=64 time=346.066 ms 64 bytes from 192.168.0.1: icmp_seq=10 ttl=64 time=347.479 ms --- 192.168.0.1 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.
