<div dir="ltr">Hi, <br><br>I got an old 10/100 switch with some new cables.<br><br>When I transfer using cross cable the speed is normal (1.5 mbps and up).<br>When I use the switch with two 5mr cables the speeds are around 150-300 kbps:<br>
<br>rsync/ssh/scp 250-300.<br>smb 150-200 kbps.<br><br>doing some tcpdump I noticed ACK retransmit around 3%.<br>I've Changed the cables. <br>iptables is not running.<br><br>I'm pretty sure I'm missing something very basic.<br>
<br>The machines :<br><br>Lenny i386 (2.6.26) and squeeze on amd64 (2.6.32)<br>I ditched the custom kernels and installed only what was in the reps.<br></div>
