We are working on enhancements that will hopefully reduce this initialization time for cold instances, which should be rolled out with the next couple of releases. There are several other threads on this, and we definitely recognize the importance and appreciate your patience.
Regarding the first post, if your file is so large that it takes 80 seconds to load it into the development server, I suggest re-structuring your application to remove this dependency. Even with the planned enhancements, it's unlikely that you'll be able to load such the complete file into main memory without hitting the 30 second deadline or triggering an out-of-memory exception. - Jason On Fri, Oct 23, 2009 at 6:06 PM, trung <tr...@phamcom.com> wrote: > > Yeah, > AppEngine drops your request after 30 seconds. > > My app takes 20 seconds to initialize in development, and half of the > times it will finish loading within 30 seconds.
