That does sound very bad. I was wondering if there might be some
network slowness in there (there was an article about this:
http://www.dd.iij4u.or.jp/~okuyamak/Documents/tuning.english.html),
however since the CPU is pegging, it must just be computational
inefficiences.

I think sending an strace log of the smbd to Jeremy would be very
useful. Unfortunately if you can't fix the code, I guess you have to
wait until someone else does. Hopefully me, once I get a bit more
freed up.

Of course Jeremy might jump in and tell me I am talking out my hat and
suggest something different!
