Well explained! In enterprise world, Java applications will benefit from 64-bit addressing. Another example is Oracle, 32-bit server side is dropped while ago. So it also make sense to compile all Oracle client linked apps with 64-bit compiler. Might be offtopic, but all above is true also for

You don't need an installer to use ppc64. Just create a chroot with debootstrap. The installer doesn't exist because we haven't had time for that yet. > On Feb 7, 2017, at 6:38 PM, Lennart Sorensen > wrote: > >> On Tue, Feb 07, 2017 at 05:28:00PM +, luigi burdo wrote: >> Sid ppc32 on X1000

Performance difference 32bit/64bit userland

Hi there, while preparing other tests I created two installations on two hosts with identical hardware (LPARs on IBM POWER): - powerpc (64 bit kernel, 32 bit userland) - ppc64 (64 bit kernel, 64 bit userland) Both are up-to-date sid with systemd held to 232-10 (#852811). Now the surprise: Using
