What is your experience guys? Is setting the default fetch

I've never had good luck with the object timestamp thing. What
ends up happening is any object you cached gets arbitrarily
refetched when you least expect it.
Well the 'object timestamp thing' is always a factor. It's not an
either/or choice. It's just a matter of time ;-) before the tsl
(timestamp lag which defaults to 1 hour) kicks into play...
Yeah, we bump ours to infinity.
Instead, what we do is all of our servers run something called
spread. (http://www.spread.org) That basically gives us a robust
broadcast messaging system so that we can publish messages to all
the servers.
We then use a category on EOEditingContext
