It makes sense that large reports take a wile to generate, allthough everything usually works fine until about 14:00/15:00 CET.. From that moment (the time the USA, Canada and other countries "at the other side" wake up), speed drops fast and the number of time outs increase rapidly. I've suggested several times (via ClientCare, summits and our account manager) to hire/buy some serverspace in Europe (and/or perhaps Asia). This might solve a lot of performance issues and makes live easier 🙂
