>a little question: if I have some "Penguins" installed on z900 (z/VM 4.4) and >I change the Big Iron with a z990, did I have any improvement if I reinstall >the linux machines? No, the code shipped by the distribution partners and all middleware I know of is optimized for the 800/900 series. No need to reinstall. You will still see the performance advantage of the new engines. Note that gcc can optimize for 890/990 too, the result would be a little faster but it would not run on 800/900 anymore.
