[Samba] High CPU load on smiod

[jools]

Hi all,

I'm running Samba 3.0.13 on Mandrake 10.2 (LE2005) and have mounted the shares 
on an NT4 server to rsync the files over to the Samba box.

The only thing is that Linux sees the dual Xeons in the server as four CPUs 
and the first core on CPU1 hits 100% while the files are copying over. Every 
so often, CPU1, core 2 takes over (at 100%) for a short period and then core 
1 goes back to 100%. Is this normal? 

When the CPU load hits 100% the mouse and keyboard become unresponsive and the 
whole plot turns clunky. I've also had to turn apic off with linux apic=off 
in Lilo.

Cheers all,

Jools
