Hi, I have problem with a Centos 5.3 computer. The networking is very slow. The networking card is a RealTek 1GigE. I plugged an Ubuntu laptop on the same cable and port with an Intel GigE, and it's about 8 to 10 times faster. So the problem is likely to be with the CentOS config. Any suggestion on how to track down the problem with speed. I have checked the packets with wireshark, no problem. Here's my ethtool eth0 output: Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Here's ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:06:7B:00:14:16 inet addr:192.168.2.103 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::206:7bff:fe00:1416/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3139398 errors:0 dropped:0 overruns:0 frame:0 TX packets:2890605 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4048643591 (3.7 GiB) TX bytes:257250846 (245.3 MiB) Any suggestion? -- Thanks _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
