THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

Before we go further, it would be better to see the benchmark result of Zstandard. I compared the compressed size and compression time of 3 1kb-sized messages (3102 bytes in total), with the Draft-implementation of ZStandard Compression Codec and all currently available CompressionCodecs. You can see the benchmark code from this commit. All elapsed times are the average of 20 1000 trials.
| Codec | Level | Size | Time | Description |
|---|---|---|---|---|
| Gzip | - | 396 | 11,543,001153 | |
| Snappy | - | 1,0635,132,056 | 37 | |
| LZ4 | - | 387 | 2,066,37357 | |
| Zstandard | 1 | 374 | 1,15256 | Speed-first setting. |

As you can see above, ZStandard outplays all existing algorithms in both of compression rate and speed, especially working with the speed-first setting (level 1).
