Most people assume that Java object serialization is faster than Jackson JSON serialization because Jackson is using JSON and Java object serialization is binary. But most people are wrong.

Jackson JSON serialization is much faster than built in Java object serialization.

Boon JSON serialization is much faster than Jackson JSON serialization.

Boon 14 snapshot

Testing the Jackson and Boon JSON serializers vs. Java Object serialization.

Boon wins by 30%. Jackson comes in third. Boon beats Java binary serialization. :)

Both Boon and Jackson kill Java serialization. Boon also kills Jackson serialization round trip.

Boon wins by a 30% margin. Jackson comes in second. Both demolish Java built-in serialization.

I recently added some optimizations to Boon JSON serialization 15 (still in snapshot). Let's see what it does to performance.

In short. Jackson is very fast. Boon is faster. And my latest rounds of optimizations did nothing. :(

Ok.. So I heard a lot about FastJson. https://github.com/alibaba/fastjson/wiki/_pages https://github.com/RuedigerMoeller/fast-serialization/wiki/TestPage Time to pony up to the bar and see how fast FastJSON is....

Round 1.

i.g.j.s.MainBoonSerializer.roundTripBig          thrpt  16         3    1      109.539      180.206    ops/s
i.g.j.s.MainFastJsonSerializer.roundTripBig      thrpt  16         3    1       77.767      442.537    ops/s

FastJSON comes out swinging. Boon lands a solid punch on the chin send FastJSON back a few steps and FastJSON wonders what just hit him.

Round 2:

i.g.j.s.MainBoonSerializer.roundTriper           thrpt  16         3    1   322589.867   263964.706    ops/s
i.g.j.s.MainFastJsonSerializer.roundTriper       thrpt  16         3    1   372651.528    60503.278    ops/s

Photo finish, but Boon comes out swinging hard, and FastJSON eeks out a small victory. Time to fire up yourKit and VisualVM.

Round 3

i.g.j.s.MainBoonSerializer.serializeBig          thrpt  16         3    1      386.978       52.936    ops/s
i.g.j.s.MainFastJsonSerializer.serializeBig      thrpt  16         3    1      143.339      130.480    ops/s

Boon body slams FastJSON. Don't call it a come back. Do you smell what the Boon has been cooking?!

Round 4

i.g.j.s.MainBoonSerializer.serializeSmall        thrpt  16         3    1   970575.272    34411.444    ops/s
i.g.j.s.MainFastJsonSerializer.serializeSmall    thrpt  16         3    1   784787.311    85672.955    ops/s

Sonic Boon! Allyoucan! Triple twirling punch to the chin. The new world champion in Java JSON serialization. The crowd roars.
