Yes, but he's using Plone, which implies not only all of the CMF
reindexing overhead, but also all the AT and Plone layers on top. That
could get even worse if he's gone to town with a workflow tool or is
using any of the truly appalling Plone addons, such as CMFMember,
This sounds like the classic abstraction vs performance debate. In the
late 80s some people criticised C++ and OOP versus C for the same reasons.
Might it not be better, rather than telling people not to use Plone +
add-ons for this reason, to just push for across the board performance
improvements, which means removing bottlenecks in Plone, Archetypes,
specific Products, as well as the underlying Zope/CMF ? Also some of the
products you are talking about may be somewhat immature and you know
what they say, don't do premature optimisation, do logic first,
performance tune later.
What you describe as "appalling" might perhaps be able to be performance
BTW CPSSkins is another performance hit. Would you care to list the
worst culprits? ;-)
