How hard would that be? I.e. what tools would we need to supply good 
profiling samples? I think we could compile a profiling-enabled 
xapian-library/omega-binary on our production-machine to generate some 
codeprofiles. Or we could copy the database to a less beafy machine, but 
that would probably skew the results towards more I/O-based than it (in 
our environment) really is.

Best regards,
