We've been doing some performance testing with an xscale NAS appliance
running the 2.6.10 Linux kernel and various versions of Samba (all other
software components remain stable while we change Samba versions).  We
see some pretty substantial performance variation between different
versions.  Is this known or expected?  Any thoughts on what could cause
the performance variation?
