A couple of simple programs for testing libp2p transport performance

Installation

$ git clone https://github.com/vyzo/libp2p-perf-test.git
$ cd libp2p-perf-test
$ go install ./...

Usage

Programs:

• test-server is the server serving a file, over TCP and QUIC.
• test-client is the client connecting to the server and downloading the served file.

The server expects a file named data to serve (can override with -data option). So let's generate a random 1GiB file and start the server:

$ dd bs=1024 count=1048576 if=/dev/urandom of=data
$ test-server
I am /ip4/127.0.0.1/udp/4001/quic/p2p/QmSfCAZ7kq8m3yuWip2gC6cE5YrpxtwDsC3wY4NMdj5a7Z
I am /ip4/192.168.2.4/udp/4001/quic/p2p/QmSfCAZ7kq8m3yuWip2gC6cE5YrpxtwDsC3wY4NMdj5a7Z
I am /ip4/127.0.0.1/tcp/4001/p2p/QmSfCAZ7kq8m3yuWip2gC6cE5YrpxtwDsC3wY4NMdj5a7Z
I am /ip4/192.168.2.4/tcp/4001/p2p/QmSfCAZ7kq8m3yuWip2gC6cE5YrpxtwDsC3wY4NMdj5a7Z

And now we can connect the client and download the data file, copying it to /dev/null.

With TCP:

$ test-client /ip4/192.168.2.4/tcp/4001/p2p/QmSfCAZ7kq8m3yuWip2gC6cE5YrpxtwDsC3wY4NMdj5a7Z
