Alternative serialization methods for WSTest

Since I've posted the WSTest results I've been wondering what the results would be when using serialization methods other than XML and what is really the difference between Aalto and SJSXP XML parsers

I've set up a test using JSON and native Java serialization. The JSON bits are handled by the Jackson processor because it's claim to fame is that it's fast and in addition to that it supports easy binding to Java objects

As always the code is available for download

WSTest (results in tps, higher is better)
Test Name	xml - sjsxp	xml - aalto	json - jackson	java serialization
GetOrder-20	8662	11632	11650	11465
GetOrder-100	4509	5126	5651	7077
EchoStruct-20	9441	12773	14788	12914
EchoStruct-100	4133	5389	6796	7575
EchoList-20	8610	12986	13889	13649
EchoList-100	3846	5129	6067	7238

What are the conclusions?

For this tests Aalto seems to be about 30-40% faster than SJSXP (the bundled StaX parser).

Jackson is screamingly fast, it gives Java serialization a run for it's money, specially for small message sizes.

It should not be impossible to beat Java serialization for simplistic requirements.

All the "infrastrsucture" Java puts up in order to serialize complete object graphs (not duplicating instances which are referenced twice and so on) sure must weight.
