Hi, In order to make an lfs live cd for old and new computer I would optimize the compilation someone sais me using CFLAGS: -Os -s -fno-strict-aliasing; I used it and I see a big difference for the size. I would know if it's possible to add -O3 for a fadtin g optimization, I tried it to a package only and not to my lfs version but I see the result : Without compilation my package 80mo With -Os -s -fno-strict-aliasing my package 14mo With -O3 -Os -s -fno-strict-aliasing my package 15,2mo I search to have fast programms and small programms
