The load tests results are not enough, I want to be more 'aggressive' and experimental. For me this package is backward compatible and do a catalog query instead of parsing all attributes. I want to do nothing except support 'talkback'. I want also to release this package on pypi, and I want your opionons:
* makina.opaquespeedup (makina is where I m working) * experimental.aggressiveopaquespeedup * any other idea ? My vote goes to experimental.aggressiveopaquespeedup _______________________________________________ Zope-CMF maillist - [email protected] http://mail.zope.org/mailman/listinfo/zope-cmf See https://bugs.launchpad.net/zope-cmf/ for bug reports and feature requests
