We had a performance problem today that we fairly rapidly determinedcame from our mail spool filesystem somehow being too slow. This waspretty impressive, because our mail spool sits on a four-way mirror on our fileservers and we could easilysee that our IO rate on its fileserver wasn't particularly large, wellbelow what we knew things could manage.
(Using NFS with a single interface makes IO rate easy to measuredirectly, no matter how complex your IO system; just look at the networktraffic volume.)

import java.io.File;import java.io.IOException;import java.io.FileNotFoundException;import java.io.FileInputStream;import java.io.FileOutputStream;import java.util.Arrays;

Suppose that you have an IMAPserver; it has mirrored local system disks, a bunch of memory, and adata filesystem (where the mailboxes are) in a RAID-10 array provided bya SAN. One day, it starts falling over unpredictably; the load averagegoes to the many hundreds, IMAP service times go into the toilet,and eventually the machine has to be force-booted. But this isn'tconsistent, and when it happens it happens very rapidly, going from anormal tiny
