Use binary data instead of string/object data

[huytd]

To speed up the connection. Send/receive data in binary format is a better idea than string/object.

[uncedric]

how would you implement that? could you point us to one example?

A starting point https://github.com/binaryjs/binaryjs

[huytd]

honestly, I have no idea how to do it. haha. that's why I put it here but not assigned to myself yet.
thanks @chrisevans1001 for the hint. I will take a look at this one.

Socket.io in current version can send binary data just like json

great!!!! 👍

There is a feedback on HackerNews, he compared the amount of data transfer by the original AgarIO game and our clone. Here is the details:
https://news.ycombinator.com/item?id=9633252

Original Agar:

• Compressed binary data
• Max packets size: 187 bytes

Our clone:

• JSON objects/String
• Packets size: 4253 bytes

There is a very long way ahead to optimize the server. First is the binary data, then, may be we will find a way to reduce packets size (only send changed values, etc)

[Azeranth]

Perhaps we could have the user compress to a BLOB format and then once it is in a BLOB the server could handle it as BLOB will move easier

[Azeranth]

If the user does the BLOB then we are utilizing some of the user resources not taxing the program

Super interesting !!! thank you

Found an interested article about Binary in JS

Somebody has done a serious research on Agar.io data structure

@huytd That Protocol.md is pretty interesting!
