[Xapian-discuss] last_mod performance

[Frank J Bruzzaniti]

I found:

http://trac.xapian.org/attachment/ticket/282/omindex-assorted-enhancements.patch

Is the implementation of last_mod to sip unchanged files in this patch 
good to use?
Are there any other patches for this laying around?

Regards,

Frank
