When planning a move from a collection of distributed systems ( intel, Sun, HP, whatever ) to Linux on zSeries - the question you are asking is not "Is Linux on zSeries Faster than platform X?" The question is "Is Linux on zSeries Fast Enough?"
In your case - will the Linux systems on your zSeries IFL be able to meet the service requirements that your customers have? The only way to know is to try them out. It looks like you already have some systems running there - ask some of your customers to try the app running on the zSeries Linux instance and see if it meets their needs. The comment that I've always heard from folks new to Z is "Where is all this capacity coming from?" For a system that has what appears to be a "slow" CPU, when it comes to real world applications it seems to be able to do more work that you would think. Unless your customers are developers, compiling code is not something that they will be doing on a regular basis so its not a valuable comparision point between intel and zSeries systems. If your customers *are* developers - then isn't it great that you can give them as many virtual machines as they need to do their development work without having to go recable/rewire/repower etc vast racks of machines on the test floor? Once they get used to the idea of a virtual development environment they may not want to go back. If they have to wait a little longer to get their tweak/compile/test cycle done is that offset by the flexibility offered by the virtual environment? In my experience, it is. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
