benchmark
We use iperf as network bandwidth measurement tool to measure transfer/bitrate among different preset combinations during a period of time.
Prerequisites
- Linux or macOS
- Node.js 8.x or above
- iperf 3.x
- blinksocks 2.5.x or above
Preparations
1. clone and install dependencies
$ git clone https://github.com/blinksocks/blinksocks
$ cd blinksocks
$ npm install
2. prepare test cases
Open and edit benchmark/cases.js, choose what you want to test.
For usage about each preset, please check out docs/presets.
3. run benchmark
$ npm run benchmark
Save stdout/stderr to files:
$ npm run benchmark > report.txt 2> error.txt
benchmark will take a few minutes to get a full report, the more test cases you added in benchmark/cases.js the more time it will spend.
4. get report
Here is an example output about network performance of different shadowsocks stream ciphers and shadowsocks aead ciphers implemented by blinksocks:

4: Test Case 2, Bitrate = 1.43 Gbits/sec, 896 Mbits/sec
[{"name":"ss-base"},{"name":"ss-stream-cipher","params":{"method":"camellia-256-cfb"}}]
Done in 61.94s.
As you can see, the program first lists blinksocks version, Operating System and Node.js Versions parameters of the current platform.
Following the parameters, there are 4 test cases, each test case has different configuration(presets) defined in benchmark/cases.js. Test results are followed by configuration line.
The first line of results represents traffic from iperf -c to bs-client while the second represents traffic from bs-server to iperf -s.
[iperf -c] <----> [bs-client] <----> [bs-server] <----> [iperf -s]

You'd better check out benchmark/iperf.sh and figure out how it works.
In my environment, stream cipher with aes-256-ctr encryption method has the maximum transfer as well as bitrate among these 4 test cases.
