That's certainly possible. Right from the beginning of this thread I've said the application address does not change, but remains at 4Gb. And that someone running non-PAE-aware applications may perfectly well benefit from running on a PAE-aware operating system such as Linux (when built with CONFIG_HIGHMEM64G).
No, it's quite the opposite! If you're running 1GiB processes, the _biggest_ performance hit you can do is run a PAE enabled kernel.
Look, I'm not saying that it makes any sense to run PAE-enabled if you've got less than 4Gb physical memory. It seems pretty obvious to me that that makes no sense whatsoever. But surely if I'm running 16 1GiB processes on my system with 16Gb physical memory, this system would benefit from running PAE-enabled rather than PAE-disabled ... ? /Per Jessen, Zürich -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com
