> Currently, JDK serialization is quite faster than Ignite's user object serialization (AllTypesMessage object):
>
> {code:java}
> Benchmark Mode Cnt Score Error Units
> SerializationMicroBenchmark.jdk_serialization avgt 15 1395605.836 ± 56061.652 ns/op
> SerializationMicroBenchmark.user_object_serialization avgt 15 3913206.848 ± 78565.118 ns/op{code}
> During the profiling and benchmarking, I've managed to get these results (I also benchmark against kryo), be aware of the change of time unit:
>
>
> {code:java}
> Benchmark Mode Cnt Score Error Units
> SerializationMicroBenchmark.jdk_serialization avgt 15 1408.451 ± 52.326 us/op
> SerializationMicroBenchmark.kryo_serialization avgt 15 2052.704 ± 102.327 us/op
> SerializationMicroBenchmark.user_object_serialization avgt 15 1963.285 ± 65.170 us/op {code}
> For simple objects (three primitive fields) I have following results:
> {code:java}
> Benchmark Mode Cnt Score Error Units
> SerializationMicroBenchmark.jdk_serialization avgt 15 948.584 ± 80.484 ns/op
> SerializationMicroBenchmark.kryo_serialization avgt 15 588.102 ± 13.152 ns/op
> SerializationMicroBenchmark.user_object_serialization avgt 15 636.171 ± 66.541 ns/op {code}
> So it seems like JDK serialization is still better for complex objects, but not for simple objects. And kryo is the best on simple objects.
