Actually since I was implementing parameter changes in the same order as you gave your suggestions, I did get a chance to compare packet size impact. I would say the difference between size=56 and 10 was perhaps a 10% improvement. The real improvement I attributed to increasing time interval- tonight I shall try some intermediate values for this. Based on "a router's inability to handle multiple ICMP request" theory, should I expect a sharp break in ping times at some interval time value, or smooth relationship between interval time and ping time?<br><br>Also, tracert usually shows at least one hop out of the three sets being above 1500. My latency for some game traffic is very poor (often above 2000) and variable. Can you suggest any tests I can do to pinpoint the cause so as to better communicate with my ISP? They seem to want to help me but don't really know how. <br><br>
