Really  thanks Niall Very interesting information

When I say is up to 30% faster is because I read some month ago a
study comparying windows and linux, and I suppose this is the reason
Oracle suggest to use Linux

But what you tell me helps me a lot because I was thinking to try to
work on linux instead of windows, now definitvely I'll get my MSCA :)
The only problem is I have to learn linux for the master certification.
