need compression?

[lifei...@gmail.com]

my app serialize objects in Kryo and record it in DB. And my app will communicate with Kryonet. I tried to compress it with Snappy after serializing with Kryo. However,  the test code means Kryo does not need compression. Does Kryo compresss internally? Is Kryonet the same? is it faster than Snappy?

User u = getRandomUser();

//2216 bytes

System.out.println("object size:" + ObjectSizeCalculator.getObjectSize(u));

byte[] serialized = serializeByKryo(u);

//1708 bytes

System.out.println("serialized size:" + serialized.length);

byte[] compressed = Snappy.compress(serialized);

//1713 bytes

System.out.println("compressed size:" + compressed.length);

KryoNet just uses your Kryo serializers. You can configure your serializers to do compression, but that is not done by default. Eg:
https://github.com/EsotericSoftware/kryo/#compression-and-encryption

I don't know Snappy. Likely Kryo data will compressed reasonably well.

thanks.  snappy seems unnecessary with Kryo or Kryonet.
