WindowsOS標準のPINGだと1ms以下の遅延は測定出来ないんです。最近CIFSを使う場合のネットワーク遅延を調べていまして、その際に重宝しました。
■True Pingの使い方
特に使い方は標準のPingと変わりません。
ダウンロード後、ping.exeと同じ
C:\WINDOWS\system32
なんかに置けばインストール完了です。あとはコマンドプロンプトから
tping Host名
でPingと同じように使えます。

Usage: tping [Options] destination-host Standard Ping Options: -t Ping the specified host until stopped. To stop - type Control-C. -a Resolve addresses to hostnames. -n count Number of echo requests to send. -l size Send buffer size. -f Set Don't Fragment flag in packet. -i TTL Time To Live. -v TOS Type of service. -w timeout Timeout in milliseconds to wait for each reply. True Ping Extended Options: -j A very simple trace route (Time To Live will increment at each ping). -p Do not use another thread for receiving data (in real applications multiple threads are used). -c Ping compatibility: Use standard data buffer: 'abcdefghijklmnopqrstuvw' (default is random data buffer). Due to compression of ip packets the standard ping buffer does not give realistic results. -d delay Delay in milliseconds between a receive and the next send 0 for no delay. Use "tping host -n 100 -d 0 > out.txt" for a high data send rate. -z count Number of echo responses to ignore in the statistic calculation. Useful if the first packets are much slower than the average packet -h Print also the Timestamp for every ping True Ping 1.13 - by Andrea Denzler :) - http://www.AndreaPlanet.com/tping/
