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.
