Bogofilter -u ??? - thread: 0.93.1 and DB_CONFIG flags

[Michael Gale]

Hello,

	I was reading the thread "0.93.1 and DB_CONFIG flags" and a comment was 
made:

--snip--
bogofilter -u is a hog and not well understood from the scoring/learning
point of view. The ostensive argumentation of "learning from known spam"
or such isn't founded on figures, and I don't dare offer my gut feeling
on this topic.

It is however well understood that -u entails write mode even for
scoring because of the subsequent registration, entails queueing behind
locks at least for the page holding .MSG_COUNT, log writes, data base
growth with unknown gains for the scoring accuracy.

I'd currently discourage the use of the -u option and if only for
performance reasons.

I checked the bogofilter.html file in the doc directory and it does warm 
against e-mail slow downs on large systems or under heavy load.

Besides the added system load ... do people find this option helps ??

I am currently using Bogofilter with the -u -p -e option on my postfix 
gateway box and any messages that are misclassified got put into a 
public folder and are automatically reclassified.

With out this option your wordlist would only get updated on error ? 
Would the "always training" be more accurate ?

Thanks.
