I've noticed since I've the dual core Opteron that my internet performance has increased significantly when my VOIP phone is in use. I don't understand it. I'm quite sure my bandwidth hasn't increased and I haven't called the company to change the VOIP settings. I accepted the hit in internet speed because of the savings in telephone bills. Is this increased in performance an anomaly or could the architecture of the CPU be responsible? This has been going on to the day since installation. Maybe it’s just a freakish columniation of events.
