Max Inden	8e2c837599	fix(perf): increase maximum udp send buffer size (#254) ... 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.	2023-08-14 16:08:41 +02:00
Max Inden	ad43602e63	fix(perf): increase root volume size (#249) ... Multiple perf runs have failed due to "no space left on device". See e.g. https://github.com/libp2p/test-plans/actions/runs/5727165977/job/15527780097. The perf terraform launch template previously did not specify a root volume size. Thus terraform used the default: ``` df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 4.0M 0 4.0M 0% /dev tmpfs 63G 0 63G 0% /dev/shm tmpfs 25G 540K 25G 1% /run /dev/nvme0n1p1 8.0G 1.9G 6.1G 24% / tmpfs 63G 0 63G 0% /tmp tmpfs 13G 0 13G 0% /run/user/1000 ``` With this commit the root volume is increased to 100GB: ``` df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 4.0M 0 4.0M 0% /dev tmpfs 63G 0 63G 0% /dev/shm tmpfs 25G 564K 25G 1% /run /dev/nvme0n1p1 100G 2.6G 98G 3% / tmpfs 63G 8.0K 63G 1% /tmp tmpfs 13G 0 13G 0% /run/user/0 tmpfs 13G 0 13G 0% /run/user/1000 ```	2023-08-04 18:50:32 +02:00
Max Inden	cfd1049e8a	fix(perf): run iperf on TCP and set TCP windows to bdp (#241) ... 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.	2023-08-04 10:23:47 +02:00
Max Inden	53ff8b5db1	feat(perf): add (automation, provision, build, run) tooling (#184) ... 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 https://observablehq.com/@mxinden-workspace/libp2p-performance-dashboard.
