Hi, There is no doubt that Linux is good at performance and flexible. But in real terms comparision made in case of Dresdner Bank migration and traditional UNIX systems as shown in articles you specefied is not acceptable it does not tell any about the age of machines they used and the version of Linux adopted for testing their application. In real time Hardware and Software must operate in sync to get maximum througput and Professional Companies like SUN, IBM have years of experience and pioneers in development their own machines and OS that can do it much better. Coming to usage of Linux on 386, 4MB machines is out of rule as you cannot install Redhat Linux 9 and Later on any machine that has less than a pentium , 64MB ram. Solaris 10 and 9 latest releases are preferred for any large OraCle installations as its most stable and scalable platform and you can read many articles at SUN and Oracle Website. In the Price game Linux always has the edge, but for a complete reliable solution you always need proprietry products
