Xapian discuss - Feb 2009 - last_mod performance

I was just wondering if anyone knew what the performance increase was 
using last_mod to only to scanned altered files.
I understand I guess it all depends on how busy the site is and how many 
files change, but typically would you say it's a feature that
you would use because of a dramatic increase in performance.

Thanks,

Frank

I've not measured it, but it will typically be quite significant.  Depends
how many files you have which aren't frequently changing, of course.

Yes.
