The dev appserver is a simulator, not a true emulator. It'll run much slower locally than in production because in production Google uses BigTable, scalable email service, scalable XMPP, scalable task executor, etc.
On a side note, this is the lesser of two evils, anyway. Anyone that has done iPhone development knows that the simulator runs FASTER in development that it does on a real device. As you can tell this leads to problems ... On Thu, Mar 11, 2010 at 2:03 PM, Karel Alvarez <[email protected]> wrote: > wow!, seriously? is this in the docs??
