Adding Petr Hejl to have a look at this too.

In GF plugin there is instance provider being initialized and it's reading configuration from disk. Slow piece of code is retrieving some class path information for maven:

org.glassfish.tools.ide.server.config.ConfigUtils#processClassPath

This can be removed from library initialization code and it can be done as lazy initialization with first maven dependencies request.

It will save approx. 1/2 of time. Another part is server instances loading (18% of time) but I would like to keep it there.

Pater, do you have an idea if this can be started as asynchronous task in infrastructure?

Comment 3 Petr Hejl 2013-08-05 06:27:20 UTC

I do see readInstanceFromFile is calling writeInstanceToFile (which takes time). Does it make sense? 

As I suggested in some other issue in case you don't need OptionalDeploymentManagerFactory.finishServerInitialization use the Proxy (learn by example in other server plugins).

Comment 4 TomasKraus 2013-08-05 15:10:14 UTC

That sounds bit weird to me but yes, you are right. This should be fixed. But it's 1/10 of total AWT queue delay. I'll have a look at proxy after all P2s will be handled.

Comment 6 Petr Hejl 2015-05-13 14:52:20 UTC

This should postpone the initialization of libraries to a time when it is really needed - web-main caf64576a7f1.
