Microsoft is pretending now, that it’s windows 2003 is faster than Linux in IBM zSeries with 3 to 4 processors, the fact is the last study operated by the third part as a contrcat, the sutdy is obiviuous and like evrytime never tells what exacts benchmarks were done and what are the real results : on word M$ you can go to hell ! if ever Win2003 server was better (if we look using M$’s eyes) Linux is always better, beacause the major Linux ditro costs about 300 $, while the M$’s baby costs at least 10 times ! and more over Opensource is illigibale !
