- [ ] Link to issue, e.g. `Resolves #NNN` - [ ] Documentation added (if applicable) - [x] Tests added - [x] Branch rebased on top of current main (`git pull --rebase origin main`) - [x] Changes squashed to a single commit (described [here](http://gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html)) - [x] Build is green in Travis CI - [x] You have certified that the contribution is your original work and that you license the work to the project under the [Apache 2 license](https://github.com/nats-io/nats-server/blob/main/LICENSE) ### Changes proposed in this pull request: - Add JetStream benchmark that measures publish throughput with different limits (MaxBytes, MaxMessages, MaxPerSubject, MaxAge, ...) - Merge `jetstream_chaos_*_test.go` and and `jetstream_benchmark_*_test.go` into two files (down from 8) Example output (filtered subset): ``` $ go test -v -bench 'BenchmarkJetStreamInterestStreamWithLimit/.*R=1.*/Storage=Memory/.*' -run NONE -benchtime 200000x -count 1 goos: darwin goarch: arm64 pkg: github.com/nats-io/nats-server/v2/server BenchmarkJetStreamInterestStreamWithLimit jetstream_benchmark_interest_stream_limit_test.go:44: BatchSize: 100, MsgSize: 256, Subjects: 2500, Publishers: 4, Random Message: true BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1 BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory/unlimited jetstream_benchmark_interest_stream_limit_test.go:230: Stream: {clusterSize:1 replicas:1}, Storage: [Memory] Limit: [unlimited], Ops: 200000 BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory/unlimited-8 200000 9743 ns/op 26.28 MB/s 0 %error BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory/MaxMsg=1000 jetstream_benchmark_interest_stream_limit_test.go:230: Stream: {clusterSize:1 replicas:1}, Storage: [Memory] Limit: [MaxMsg=1000], Ops: 200000 BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory/MaxMsg=1000-8 200000 9800 ns/op 26.12 MB/s 0 %error BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory/MaxMsg=10 jetstream_benchmark_interest_stream_limit_test.go:230: Stream: {clusterSize:1 replicas:1}, Storage: [Memory] Limit: [MaxMsg=10], Ops: 200000 BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory/MaxMsg=10-8 200000 9717 ns/op 26.35 MB/s 0 %error BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory/MaxPerSubject=10 jetstream_benchmark_interest_stream_limit_test.go:230: Stream: {clusterSize:1 replicas:1}, Storage: [Memory] Limit: [MaxPerSubject=10], Ops: 200000 BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory/MaxPerSubject=10-8 200000 78796 ns/op 3.25 MB/s 0 %error BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory/MaxAge=1s jetstream_benchmark_interest_stream_limit_test.go:230: Stream: {clusterSize:1 replicas:1}, Storage: [Memory] Limit: [MaxAge=1s], Ops: 200000 BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory/MaxAge=1s-8 200000 9648 ns/op 26.53 MB/s 0 %error BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory/MaxBytes=1MB jetstream_benchmark_interest_stream_limit_test.go:230: Stream: {clusterSize:1 replicas:1}, Storage: [Memory] Limit: [MaxBytes=1MB], Ops: 200000 BenchmarkJetStreamInterestStreamWithLimit/N=1,R=1/Storage=Memory/MaxBytes=1MB-8 200000 9706 ns/op 26.38 MB/s 0 %error PASS ok github.com/nats-io/nats-server/v2/server 26.359s ``` cc: @jnmoyne
