SysInternal tools are a great suite of tool provided by Mark Russinovich and his team. Each tool of this collection is a valuable tool. PSPING.EXE is not an exception.
“PSPING.EXE is aa command-line utility for measuring network performance. In addition to standard ICMP ping functionality, it can report the latency of connecting to TCP ports, the latency of TCP round-trip communication between systems, and the TCP bandwidth available to a connection between systems. Besides obtaining min, max, and average values in 0.01ms resolution, you can also use PsPing to generate histograms of the results that are easy to import into spreadsheets.”
