Hello. Recently I bought a new notebook computer with 64-bit AMD CPU and installed SuSE x86_64 on it. The speed is significantly slower then my old notebook computer. In order to tell if this is an OS problem or hardware problem, I installed Windows on both computer and tried again. Both have 512MB memory. I. Windows OS on new notebook is *significantly* faster then Windows on my old notebook; II. SuSE x86_64 on new notebook is *significantly* slower then SuSE x86 on my old notebook. I think probably memory is the key problem, SuSE x86_64 once start up gnome desktop environment, without running any application, can eat up 400MB memory. If I run yast the difference is more obvious: on SuSE x86_64 running yast with software management, free(1) tells 400MB physical memory is used (rest of physical memory are cache), 400MB swap space is used, all together 800MB. I just suspect that probably running SuSE x86_64 might use as twice as memory of that x86_32 version? In that case I probably better choose SuSE x86_32.
