Right.

I keep a largish local nntp storage (from opensuse nntp forum) with
leafnode, stored on a reiserfs partition, and it takes a huge time to do a
local text search. Millions of files to look at.

I don't know about NNTP, but email is usually indexed, at least by date, most likely subject and sender and possibly by mail-ID. Dovecot also has the option of using something like Plucine for full text indexing for the body.

IIR NNTP headers aren't that different from email headers; perhaps dovecot could be persuaded to manage and index those files :-)

Yes, there are indexes.

There is the folder "/var/spool/news/opensuse/org/help/applications/", for example, with 12000 files, each one a single post, complete (headers and body). But there is also a ".overview" file which is, I guess, a binary index of those posts.

And there is also the folder "/var/spool/news/message.id/", which contains a thousand directories named "000" to "999", and each directory contains many posts, or none, each a single file with headers and body.

I guess that those files in the first structure are hardlinks to those in the second structure.

There is not a content index. If I want to do a body text search, I have to do a filesystem grep on one of the structures, and it takes ages. Likewise, thunderbird does not offer to do body text searches.



Btrfs? I don't know how it compares to reiserfs in terms of small files.

Target is 'same or better'. I have no complaints about performance; I just wish the fsck on boot actually did something :-/

Ah, yes, that is keeping me out :-(


Absolutely!

A mind is a terrible thing to waste when a computer could be programmed to do that boring, fiddly jobs so much better. Computers don't get distracted, don't turn of for work late with a hangover, don't have BOFH mentality (no, really). As Norbert Weiner said "Render unto the computer the things that are the computer's and unto man the things that are mans'". Doing the computer's job is no job for humans.

:-)

Right.
