JsonSchemaFactory.byDefault() too slow

[Alfredo F]

Hello,

Invoking method JsonSchemaFactory.byDefault() in my computer takes too long (over 2.5 seconds). This only happens the first time it is invoked, all future invocations are quick.

My computer is relatively new and it isn't particularly slow (Intel i5) 

Is this normal? Do others have the same experience than me? What can I do to improve this?

Regards,

Alfredo
