JSON Parse very slow

[therevills]

I’ve created a little map via PyxelEdit, it is 640×400 in size using 8×8 tiles (so 80×50) and I’m using 3 layers, I’ve exported it into JSON format and when trying to parse it is taking over a second:

Monkey

[crayon-5c81dccaaefdb608847426 inline="true" ] Local json := LoadString("asset::levels/" + mapFileName + ".json") Local st:=Millisecs() jsonData = JsonObject.Parse(json) Local et:=Millisecs() - st Print "JSON Parser took " + et + "ms"

1 2 3 4 5

[crayon-5c81dccaaefdb608847426 inline="true" ] Local json := LoadString("asset::levels/" + mapFileName + ".json") Local st:=Millisecs() jsonData = JsonObject.Parse(json) Local et:=Millisecs() - st Print "JSON Parser took " + et + "ms"

Here is a subset of the JSON:

[crayon-5c81dccaaefe1531124714 inline="true" ]{ "tileshigh": 50, "tileheight": 8, "tileswide": 80, "tilewidth": 8, "layers": [ { "tiles": [ { "x": 0, "rot": 0, "y": 0, "index": 0, "tile": -1, "flipX": false }, { "x": 1, "rot": 0, "y": 0, "index": 1, "tile": -1, "flipX": false }, { "x": 2, "rot": 0, "y": 0, "index": 2, "tile": -1, "flipX": false },

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

[crayon-5c81dccaaefe1531124714 inline="true" ]{     "tileshigh": 50,     "tileheight": 8,     "tileswide": 80,     "tilewidth": 8,     "layers": [         {             "tiles": [                 {                     "x": 0,                     "rot": 0,                     "y": 0,                     "index": 0,                     "tile": -1,                     "flipX": false                 },                 {                     "x": 1,                     "rot": 0,                     "y": 0,                     "index": 1,                     "tile": -1,                     "flipX": false                 },                 {                     "x": 2,                     "rot": 0,                     "y": 0,                     "index": 2,                     "tile": -1,                     "flipX": false                 },

If I export to XML and parse it via tinyxml it only takes around 300ms.

The JSON is pretty big though over 2MB in size, but even compressed its slow.
