A mobile phone might instantiate a module (main program or shared library) a few thousand times per day, while a desktop/server often instantiates a module many thousand times per minute. Thus the initial costs of processing the relocation table often do not matter on the phone, but can be significant on the desktop/server
you missed a important post of another person _________________________________________________________________________ iOS 4.3 or later, and OS X 10.7 or later, fully support PIE executables; moreover, applications submitted for distribution via Apple's App Store are required to be fully position-independent In OpenBSD, the amd64 and other platforms have been switched to PIE (position-independent executables) by default _________________________________________________________________________I don't want to go the road where press articles say a specific bug in software XYZ available for Linux, BSD and OSX would have only on Fedora not been mitigated because we still discuss over performance impacts while others already went ahead
https://fedoraproject.org/wiki/Foundations First represents our commitment to innovationI would welcome Fedora be first in things like this topic instead as often in the past replace already working things with unfinished alpha quality and need 3 follow-up releases to get back from where it came and praise "new things" which are in fact regression-fixes and features which where there before the replacements
