QUIC vs TCP performance measurement tools

Build

Before obtaining a runnable executable file you'll have to run go build qtm.go to build the program. A main.exe file will be created right next to the qtm.go file in the root of the repository.

qtm is the name of the tool, which is short for "QUIC / TCP measurement".

Try executing it from the command line: qtm.exe or qtm on the command line!

Application modes

You can start the command line measurement tool in either server or client mode. To start the tool in server mode append the flag --server on startup. If you omit the --server flag the tool is started in client mode by default.

Start tool in client mode

qtm

Start tool in server mode

qtm --server

Usage

Tool syntax:

qtm <flag 1> <flag 2> ... <flag n>

The flags can be in the format -server or --server

Connection Type

There are two connection types available:

• TCP
• QUIC

Set the connection type either if you configure nothing (The used connection type is QUIC) or if you provide the --type flag with the connection type. Example: qtm --type=TCP.

Measuring Throughput

In order to measure the throughput, you can either use:

• --bytes (Example: qtm --bytes=10000000) to send the set amount of bytes
• --duration with --buffer-size where you'll send for the set duration in chunks of the set buffer-size. (Example: qtm --duration=5s --buffer-size=1024)

TCP measuring example

Start the server with:

qtm --server --type=TCP

Start the client with:

qtm --type=TCP --bytes=100000000
