See: //test/benchmarks/build/bazel_test.go.

The harness will handle any presetup that needs to happen with - flags, remote virtual machines (eventually), and other services. -* Respect `b.N` in that users of the benchmark may want to "run for an hour" - or something of the sort. -* Use the `b.ReportMetric()` method to report custom metrics. -* Set the timer if time is useful for reporting. There isn't a way to turn off - default metrics in testing.B (B/op, allocs/op, ns/op). -* Take a look at dockerutil at //pkg/test/dockerutil to see all methods - available from containers. The API is based on the "official" - [docker API for golang](https://pkg.go.dev/mod/github.com/docker/docker). -* `harness.GetMachine()` marks how many machines this tests needs. If you have - a client and server and to mark them as multiple machines, call - `harness.GetMachine()` twice. - -## Profiling - -For profiling, the runtime is required to have the `--profile` flag enabled. -This flag loosens seccomp filters so that the runtime can write profile data to -disk. This configuration is not recommended for production. - -* Install runsc with the `--profile` flag: `make configure RUNTIME=myrunsc - ARGS="--profile --platform=kvm --vfs2"`.

For example, to -generate a CSV for various latencies, you might do: - -``` -rm -f /tmp/netstack_latency.csv /tmp/native_latency.csv -latencies=$(seq 0 5 50; - seq 60 10 100; - seq 125 25 250; - seq 300 50 500) -for latency in $latencies; do - read throughput client_cpu server_cpu <<< \ - $(./tcp_benchmark --duration 30 --client --ideal --latency $latency) - echo $latency,$throughput,$client_cpu >> /tmp/netstack_latency.csv -done -for latency in $latencies; do - read throughput client_cpu server_cpu <<< \ - $(./tcp_benchmark --duration 30 --ideal --latency $latency) - echo $latency,$throughput,$client_cpu >> /tmp/native_latency.csv -done -``` - -Similarly, to generate a CSV for various levels of packet loss, the following -would be appropriate: - -``` -rm -f /tmp/netstack_loss.csv /tmp/native_loss.csv -losses=$(seq 0 0.1 1.0; - seq 1.2 0.2 2.0; - seq 2.5 0.5 5.0; - seq 6.0 1.0 10.0) -for loss in $losses; do - read throughput client_cpu server_cpu <<< \ - $(./tcp_benchmark --duration 30 --client --ideal --latency 10 --loss $loss) - echo $loss,$throughput,$client_cpu >> /tmp/netstack_loss.csv -done -for loss in $losses; do - read throughput client_cpu server_cpu <<< \ - $(./tcp_benchmark --duration 30 --ideal --latency 10 --loss $loss) - echo $loss,$throughput,$client_cpu >> /tmp/native_loss.csv -done -``` diff --git a/test/benchmarks/tcp/nsjoin.c b/test/benchmarks/tcp/nsjoin.c deleted file mode 100644 index 524b4d549..000000000 --- a/test/benchmarks/tcp/nsjoin.c +++ /dev/null @@ -1,47 +0,0 @@ -// Copyright 2018 The gVisor Authors. -// -// Licensed under the Apache License, Version 2.0 (the "License");
