Very slow network performance

[litz]

I have a Rawhide networking issue ...<br /><br />I get max speed on any network interface of 50-60k/s ... this happens irrespective of :<br /><br />kernel version (from the original 2.6.8-1.541 FC3 kernel to the latest Rawhide (2.6.10-1.1146_FC4 ...<br /><br />Net card hardware type (tried every kind of card I can get my hands on)<br /><br />Switch it's plugged into<br /><br />System it connects to (other linux, windows, or systems across the internet)<br /><br />Actual interface (eth0, eth1, etc.)<br /><br />Even have tried creating dummy devices and transferring between them, same result.<br /><br />Happens with firewall on or off ...<br /><br />System is current to latest yum update downloads, was originaly a FC3 default server install, with yum set for updates gotten from : <a href="ftp://mirrors.kernel.org/fedora/core/development/$basearch/" target="_blank">ftp://mirrors.kernel.org/fedora/core/development/$basearch/</a><br /><br />There are, of course, exactly zero 
 errors listed in any log file.<br /><br />This has me totally baffled.  I can't trace it to a particular kernel version or hardware cause.<br /><br />Anyone have any ideas?<br /><br />thanks<br /><br />- litz
