But it requires modifications to the OS, modifications which (AFAIK) have not been done for Linux (yet). Also as has been previously noted multi-processing raises caching and locking issues which will degrade system performance in some areas, and some applications are incapable of taking advantage of SMP. As a general rule 2*1GHz processors will deliver less performance than 1*2GHz processor even if the applications can take advantage of SMP! Also it appears from Intel's web site that a processor designed for non-SMP use can be obtained at a higher clock rate than an SMP capable processor... I don't think that 2 CPUs is a benefit. If you've got an option of 4+ CPUs then it may be worth having though. -- I do not get viruses because I do not use MS software.
