Has anyone figured out the > ideal compiler flags? Probably there is one or two applications that would benefit from -O3, but the total effect on KDE might be bad (it will use more i[nstruction]cache and L[evel]2 cache) Read this news item by Linus (on comp.arch) Since KDE is object oriented(== lots of small functions everywhere) I would guess that our problem is even bigger... Anyone having recent cachegrid results? A smart optimizing linker(!) could help more than any compiler option. /RogerL -- Roger Larsson Skellefteċ Sweden >> Visit http://mail.kde.org/mailman/listinfo/kde-devel#unsub to unsubscribe <<
