# Channel Benchmark Results
|
|
|
|
|
|
|
|
|
|
This documents lists several benchmark results for different platforms in order to
|
|
|
|
|
identify performance regressions and improvements.
|
|
|
|
|
|
|
|
|
|
The are measured using the command
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
> channel_bench_* <nsend> <nrec> <buflen> <nobj>
|
|
|
|
|
|
|
|
|
|
nsend ... number of threads that push objects into the channel
|
|
|
|
|
nrec .... number of threads that pop objects from the channel
|
|
|
|
|
buflen .. length of channel buffer queue - `0` means unbuffered channel
|
|
|
|
|
nobj .... number of objects to pass thru the channel
|
|
|
|
|
```
