Re: Slow network performance
This sounds like your switch and host settings are correct so I wouldn't spend too much more time looking at that at this point. I just wanted to mention it to be sure. Good luck!

Thanks Vinny Abello writes: Although I don't think this is necessarily the cause of your dropouts as you put it, one must understand the way autonegotiation and manual speed and duplex work between network gear. For autonegotiation to work, BOTH devices must support autonegotiation, OR both devices must be set to the same speed and duplex setting. If one only supports auto and the other does not, you must NOT set the device that you can manually configure to full duplex. The auto device will never negotiate at full duplex and fall back to half when autonegotiation fails, causing a duplex mismatch and horrible network performance and loss. A very rough set of rules of thumb (YMMV): When connecting to an unmanaged switch, use auto. If your host doesn't support auto, set it to half-duplex. When connecting to a managed switch, make sure the port is set to auto and set your system to auto, otherwise force both the switch port and your host to the same settings. This is required especially if the host doesn't support auto negotiation and you want to run at full duplex. When connecting to a managed switch, enable portfast or the equivalent spanning-tree command on the switch port your host is connected to so it forwards traffic immediately when getting link. So to sum it up, auto only works if both sides speak auto. Auto negotiation failure falls back to half-duplex! Of course there are all the horror stories where auto negotiation is evil and that different vendor's implementations don't play nice or are just completely broken, so always set things to manual or you and your family will suffer an untimely death... There are so many of these stories that one would think there has to be some truth to it. In my own experience, I have never had an issue with auto negotiation in some ten years of working with a dozen different vendors' networking gear so I guess I'm lucky... or I just understand how it interacts with other devices and their capabilities. I still don't know which exactly. Hope this helps! :) Dimuthu Parussalla wrote: Hi All, Apart from random dropout from the network. Our IBM X236 server suffers slow network performance. I've changed the server from CISCO switch to a netgear switch on a test platform. Also tried 1000m full-duplex setup with no auto negotionation on both ends. Still after few days (3-4) server drops the connection. And while its working I get 90KBps upload/download with ftp transfers. I have treid changing BGE network cards to EM (intel 100/1000) still the same result.
