Many beings have told me that they have built a clustered system and jobs ran actually slower due to a non optimized cluster. From what I understand about clustering (which isnt much), one needs to hone everything on the cluster to a fine edge inorder to realize any performance gains. "What the "tweakable" variable are exactly and just how to tweak them is a job only a "DEC cluster consultant" can tell us", I am told. Good luck!!! Sincerely, Mitchell
