Yes, it's inside GAE application. Intellij Idea is using AppMain to run
the DevAppServerMain app by providing and exploded directory of my project.

Hello,
I'm encountering similar issue with Guice. Currently the
initialization time of my application is for about 12 seconds.
(From my log: Injector Initialization Time:12023 ms). On my local
development machine it's initialized for Time:4982 ms.
Here is some logging snippets from my local environment that are
showing execution time of the initialization operations:

Any idea how I can optimize my application ?
I was thinking for using of child injectors and late bindings, but
currently I couldn't find out clean way to do it.

Miroslav

Do you have a lot of AOP running? That could be making GAE run
additional classes through the security loader.

Yes but pre-compilation does not affect Guice startup time.

John,
Enable FINE-level logging for Guice's Stopwatch:
Logger stopwatchLogger =
Logger.getLogger(com.google.inject.internal.Stopwatch.class.getName());
stopwatchLogger.setLevel(Level.FINE);
This will log perf #s and tell you at a high level where
the time is spent during injector creation.
Beyond that, I'd use a profiler like YourKit.
Unless you have a ginormous configuration, my guess is
something expensive is happening in one of your modules.
4 seconds sounds excessive. I use Guice on Android, even
going so far as to create a separate injector for each
screen, and startup time hasn't been an issue.

Hi, I am using Guice with a Google App Engine
project but have found
that the startup time of Guice is killing my app.
"Loading requests"
are very frequent in GAE and need to be fast or your
user sits and
waits. Currently the apps startup time is about 6
seconds and of that
the Injector takes 4 seconds to build. This is with
Stage set to
Development which did knock about two seconds off
the time.
My question is, are there any other tricks to reduce
Guice startup
time. Could some configuration be saved or
serialized rather than
recalculated every time my app spins up a new instance?
Thanks,
John.
