Even if it isn't a cache miss now, it might become later as there will be more cachelines touched by the iteration. That means some older cachelines were evicted from L1, which means you'lll most likely get a cache miss elsewhere that could've been a cache hit. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
