Hello List, I want to learn how a cpu type change effects my application performance. When a new generation mainframe is produced, it comes with hundreds of new instructions. I think that new instructions run applications more efficiently than the previous ones. Also for example if i had a 1000 MIPS capacity 1 CPU old machine, the new generation mainframe comes with 1200 MIPS capacity per CPU. If I think like, "the number of mips increased also the instructions will be more efficient than the previous ones. So my total gain is bigger than the mips capacity increase", is that idea correct or not ? Or is that directly related with the operating system version? If i dont upgrade my z/OS, will i able to get the benefit of new instructions? I hope i could explain myself. Thank you.
