[Zope] multiple Zope connections to the same database within different branches

Hi list. I'm just curious, if you've got two connections to the same database in 2 different branches at the same level, is it better to put those 2 connections in the 'trunk' of those two branches. Is there performance reasons to do so/ not to do so? for example ZopeRoot ---branch1 --- dbconn billybob ---branch2 --- dbconn billybob as compared to ZopeRoot ---dbconn billybob ---branch1 ---branch2 Say also, if branch1 experiences much more traffic than branch2 (which is the case in my installation), is this much of a consideration? Are there any other issues here which I would need to be aware of? Cheers, Julian
