Ubuntu To Stop Offering 32-Bit ISO Images, Joining Many Other Linux Distros (bleepingcomputer.com)
An anonymous reader writes: Canonical engineer Dimitri John Ledkov announced on Wednesday that Ubuntu does not plan to offer 32-bit ISO installation images for its new OS version starting with the next release — Ubuntu 17.10 (Artful Aardvark) scheduled for release on October 19. The decision comes after month-long discussions on the dwindling market share of 32-bit architectures. Ledkov made it clear that Canonical does not plan to stop support for 32-bit architectures. The Ubuntu team plans to continue to offer security updates and bug fixes, but they won't be offering new ISO images. Lubuntu and Xubuntu, which are Ubuntu offshoots created to run on older computers, will most likely continue to provide 32-bit ISO images, as this is their bread and butter. Manjaro, Tails, and Arch Linux announced similar decisions. Even Google dropped support for Chrome on 32-bit Linux platforms, way back in 2015, predicting the overall trend.
No, you are wrong. If you want performance AND you want 32-bit pointers you can use https://en.wikipedia.org/wiki/...
Then you get the benefit of 16 64 bit GPRs, PC-relative addressing and other features that INCREASE performance. There is no good reason to run a 64-bit x86 OS in 32 bit mode.
