Question

Suppose I use the standard Java object serialization to write/read small (< 1K) Java objects to/from memory buffer. The most critical part is the deserialization, i.e. reading Java objects from memory buffer (byte array).

Is there any faster alternative to the standard Java serialization for this case ?

Answer 1

have a look at kryo.
its much much faster than the built-in serialization mechanism (that writes out a lot of strings and relies heavily on reflection), but a bit harder to use.

edit: R.Moeller below suggested FST, which i’ve never heard of until now but looks to be both faster than kryo and compatible with java built-in serialization (which should make it even easier to use), so i’d look at that 1st
