cjson serializes json into two parts, scheam, which stores the structure data of json, and value, which stores the value of json. For a large number of json data with similar structure, the space for storing duplicate schemas can be saved.

|---|---|---|---|---|---|---|
| 275 | 172 | 62.55% | 134 | 48.73% | 306 | 111.27% |
| 152 | 106 | 69.74% | 81 | 53.29% | 187 | 123.03% |

| 5473 | 1321 | 24.14% | 1956 | 35.74% | 3277 | 59.88% |
| 12337 | 2561 | 20.76% | 4360 | 35.34% | 6921 | 56.10% |
In an ideal case, ignoring the relatively small amount of scheam storage, a compression ratio of about 35.34% can be achieved with gzip enabled.
The json for the tests is contained in the
cjson/cjson_test.gofile.
