Actually, this is not from reading the docs.  It is from being burnt a 
few times by
getting "impossible" time values.  By the way, I am replying to you and 
to the mailing
list, but messages to you are getting bounced.

Which numbers don't look right?  3 of your reads took between 2 and 4 
milliseconds, most were between
8 and 16 nanoseconds.  21 writes took between 2 and 4 milliseconds, the 
most amount of time
spent doing read/write by host is about 1.2 seconds, and teste/file10 
took about 1.1 seconds.
Looks pretty good to me.(?).  I'm curious about what you were expecting 
to see.
