Kubuntu uses GCC 4.3.3 compared to=20 =46reeBSD's GCC 4.2.2. There is a considerable performance difference betw= een=20 the two OS's, the article contributes this difference to the compiler. =20 In order to check if this is so (and to get the speed improvements of GCC=20 4.3+) one needs to compile the ports (and preferable world/kernel as well)= =20 with GCC 4.3+. =20 Is there an easy way to set this up and does anyone know the compatibility = of=20 world/kernel/ports with GCC 4.3+? Also has anyone tried this and benchmarked the result?
