I tried with -o nounix and it too did not make any perceptible difference in traversal time. So, I booted the older system off of the Ubuntu live cd (same version that I used to setup my newer, slower machine) mounted the share, and performed an ls -R a number of times. In each instance, it was just as slow as my newer system. This pretty much rules out some sort of hardware issue.<br>
<br>I will do as you suggested and get some captures from both systems, then post them to see if that will yield some more information.

</div>Ok, good to check. Other than the change to server inode numbers, I'm<br>
not sure of any huge changes to the readdir code recently. You could<br>
try mounting with '-o nounix' to disable unix extensions. I'm not sure<br>
what the state of those was around 2.6.21.<br>
<br>
The more you can do to narrow it down, the better. If you can rule out<br>
hw changes, then you might get some wire captures while doing this on<br>
the old and new kernels and look for the differences there.<br>
