designing high performance j2ee distributed application

Hi all,

I am currently working on designing a SOA based distributed J2EE application where high performance is the main criteria(data retrival must be very fast). The database and application servers can be many in number and in different geographical locations.

I would like to know the various industry standards/strategies used in real world for designing the GUI, business and database layer for high performance.

Is there a way to know about the case studies of the real world applications like airlines and stocks trading(where real time updates retrival must be real fast).

Please point me to any good articles/white papers/web sites/books

if any.

Thanks in advance.
