Might mention here that the primary reason you'd probably want to *not* 
use wireformat is if you have some old existing software that grovels about
in the spool and was written for the traditional article layout/format.

Occasionaly one does need to modify this one.  If you're having problems
with channel feeds keeping up, setting this value low (2-3 seconds) helps a lot
as when the channel feed backlogs and the pipe fills, innd will only wait 2
seconds to try again, instead of 2 minutes.

IMHO, this default is rather low (think about it, that's flushing the active
file to disk almost every *second* on a system with a fairly full feed.)  I
usually run with 1000, myself.  Of course, for an innd that gets little
traffic (say one set up just to gate some mailinglists into newsgroups) 
waiting for 1000 articles to come in may be too much, and 10 be just right.
