Has anyone experienced performance degradation when backing up large
volumes of files from a NAS array? I am researching complaints that
backing up large volumes of small files (128k)results in a noticeable
performance drop. One suggested solution was to segregate small files
and back them up over the LAN rather than the SAN. Does this make
sense?

Thanks,

Is this thru an ethernet switch ? FWIW I once saw a _very_ strange
problem that sort of fit your description. After eliminating lots of
things, I sort of narrowed it down to the switch (an otherwise
excellent HP procurve box in use for a year.) A call to HP support
told me quickly that it was a "known problem" and that I should reboot
the swicth. If the problem reoccured there was a microcode update
avaiable.

FWIW
