The problem specifically seems to be that classloading is slow. A significant part of that is explained by slow network I/O, but not all; for example, getting AOP proxies built and loaded seems to take significantly longer than one would expect by profiling locally. I speculate that the extra security measures of GAE's sandbox are also taking a toll. Jeff -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
