Instead of using dual CPUs or networking, my system engineer had helped me to design a workstation having the raid 0 structure using two harddisks. The result does suppot a very stable speed up to about 105,000 to 120,000 kb/s using one P4 3.06G HT processor and 1G of ram. Besides, seems to me this method is less expensive when compared to dual CPU system (especially if poser 5 does not take advantage of the second CPU...) ^_^ TK
