This was accomplished by shrinking the on-chip feature size, which allowed increased switching speed and decreased power consumption, and also enabled speedups via complexity: pipelines, superscalar/out-of-order execution, etc, etc. The recent clock speed plateau notwithstanding, the number of transistors keeps increasing. ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
