Various `quinn*` crates depend on `tracing`. `tracing` in its default feature
set includes `tracing-attributes` in order to expose `#[instrument]` procedural
macro in `tracing::instrument`.
None of `quinn*` make use of the `#[instrument]` macro. Thus the
`tracing-attributes` dependency is unused.
To remove the dependency from the tree, this commit restricts `tracing`'s
`features` to `std`, effectively removing the `attributes` feature.
This commit updates Quinn's dependency on Rustls from v0.20.3 to
v0.21.0.
This release includes a handful of small breaking changes which are
resolved alongside the upgrade.
In order to extend the bulk benchmark further, this change moves most
common functions out of the bulk.rs binary and into a lib.rs and stats.rs file.
Functionally there are no relevant changes.
This causes nom to be pulled in, which currently causes the CI error and build
conflict between `funty` and `bitvec`: https://github.com/myrrlyn/funty/issues/3
We don't need the feature in this scenario anyway.
This extends the benchmark to make the consumer either utilize the
ordered or unordered read API.
The ordered read API is now set to the default, since it might be
applicable to more applications.
This change improves the bulk benchmark:
- The total amount of requests the benchmark performs can be configured
- The amount of concurrent requests on a given connection can be
configured
- The amount of data to transfer per stream can be configured
E.g.
```
bulk --streams 300 --max_streams 100 --stream_size 10
```
will create 300 streams - with a maximum of 100 active streams at a time,
and send 10MB of data on each stream.
The "short" cli flags are taken form h2load where applicable.
The benchmark now also shows metrics which indicate the performance
of individual streams, which allows to judge fairness. Example output:
```
Overall stats:
Sent 3145728000 bytes on 300 streams in 12.11s (247.81 MiB/s)
Stream metrics:
│ Throughput │ Duration
──────┼───────────────┼──────────
AVG │ 149.17 MiB/s │ 396.00ms
P0 │ 0.83 MiB/s │ 39.00ms
P10 │ 51.19 MiB/s │ 40.00ms
P50 │ 129.75 MiB/s │ 77.00ms
P90 │ 247.00 MiB/s │ 195.00ms
P100 │ 254.75 MiB/s │ 12.11s
