cargo run
|
||
|

## Performance
|

|
|
This implementation serve thousand of clients on a 2013 macbook air without problems.

Run [benchmark.js](benchmark.js) to benchmark your own system:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ node benchmark.js
|
||
|
|
Connected: 1000, connection time: 867 ms, total broadcast time: 23 ms^C⏎
|
||
|
|
```
|
||
|

### Error *Too many open files*
|
||
|

You may be limited to a maximal number of connections (open file descriptors). Setting maximum number of open file descriptors to 2048:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
ulimit -n 2048
|
||
|
|
```
|
||
|
|
|
||
|
|
Test maximum number of open connections with [drain.js](drain.js):
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ node drain.js
|
||
|
|
Connections dropped: 5957, accepting connections: false^C⏎
|
||
|
|
```
|
||
|
|
|
||
|
|
_Accepting connections_ indicates wheter resources for the server have been exhausted.
