Well, I know that my calculations are not objective and so on, but in any case, I can not wait to wait so much time when performing my unit tests:
It takes about 7 seconds to initialize to run my swice swice application. This is a simple IRC client. At this moment, the connection is not open, I have not even named the classes java.io or java.net yet. I tried to narrow down what exactly is wrong, and I get that Guice uses 5.8 seconds (on average) to create an injector using the 2 modules that I use (one normal module and one built with FactoryModuleBuilderinstalled in the original module).
When I remove all modules (therefore mostly just for calling and for sure Guice.createInjector()), it still takes 3.5 seconds.
The version of Guice I am using is 3.0 rc2. My computer, of course, is not the latest, but it is still not older than three years.
So how can I improve Guice performance if possible?
For reference, here is the main method that I use, calling 3.5 seconds. Subsequent calls take 0.01 seconds.
public static void main(String[] args) {
long t = System.currentTimeMillis();
Injector injector = Guice.createInjector();
long t1 = System.currentTimeMillis();
System.out.println(((t1 - t)) / 1000.0);
}
And the result
3.578
