Not directly: on the application side, wrapping the
write(2) in calls to a timer will suffice.

Ah: different question.
I haven't thought about a "single statistic" for Samba:
they usually require a better brain than I have (;-))
Stealing an idea from the Unix definition of "load", we
might report the number of SMBDs waiting for disk i/o
and the number either wating for CPU or running. That
would be a "figure of merit" that might well match the
intuitive definition of "how hard is samba working"....
