We can remove the bug caching from milestones to the detriment of some large projects. There were and continue to be timeouts--caching never fixed the core issue, and it was not intended. The issue really is having time to work on milestones. We can remove all caching, or some, like bugs, blueprints, or activity. I do not expect the timeouts to return to their peaks because I landed a branch that addresses the expensive permission checks on bugs. ProjectGroups are more likely to timeout since the aggregate milestones from their projects. Do we want to remove caching from ProjectGroups too? The real issue appears to be the diversity of objects in play, bugs, specs, *and* users. The formatting of users and bus can be very expensive. Some may recall I sent out an email about the cost of formatting 250 users with icons--icons that rarely change. bugs get expensive because we decorate them with badges. We remove bug tags after a day on edge because that lead to timeouts on small projects. In general, developers need to see a lot of information to plan a release and the proposed solution of AJAX and/or batching requires feature-class planning. My calendar is booked until 2011, so fixing milestones requires the assistance. -- __C U R T I S C.
