I did more tests and I found that the problem is logging: if I comment the line [b]Logger.getLogger[/b] then it takes 10 seconds on V3, more or less same as V2. I don't know why.
I'm still looking why it's singleton on V2 but no-singleton on V3. I tried javax.ejb.Singleton and javax.inject.Singleton annotations but they don't work.
Any help?
