[Xapian-devel] How to count I/O consuming in OProfile while profiling xapian

[freebsdj]

Hi,

I have tried to profile xapian, according to the Wiki:
http://trac.xapian.org/wiki/ProfilingXapian, we can profiling I/O bound
cases with oprofile, but from many other articles, it seems that we can not
do it in oprofile.

I have followed that wiki page, installed oprofile and libc6-dbg, but it
doesn't work, only CPU bound functions are counted.

Anyone know how to count I/O cost in oprofile? Many thanks!

Best Regards!
