Previously only the maximum udp **receive** buffer size was increased to
`2500000` bytes. With this commit both the send and the receive buffer size is increase.
This commit makes iperf use TCP instead of UDP. Using UDP allows the sender to
send as much data as they can, not as much data as the receiver can handle.
Using TCP measures the actual bandwidth of the connection.
This commit sets the TCP send and receive window to the bandwidth-delay-product.
In order to exhaust the whole bandwidth between the two nodes, TCP needs to be
able to buffer all bytes on the wire in the case of packet loss.
This project includes the following components:
- `terraform/`: a Terraform scripts to provision infrastructure
- `impl/`: implementations of the [libp2p perf
protocol](https://github.com/libp2p/specs/blob/master/perf/perf.md) running on
top of e.g. go-libp2p, rust-libp2p or Go's std-library https stack
- `runner/`: a set of scripts building and running the above implementations on
the above infrastructure, reporting the results in `benchmark-results.json`
Benchmark results can be visualized with
