android: gson performance

Question

I am trying to use gson to do my object mapping on the android emulator.

It has been ridiculously slow when processing json data around 208 kb. I do not have any hie

Answer 1

I have found that CREATING a Gson instance is a very expensive operation, both in terms of CPU used and memory allocated.

Since Gson instances are thread-safe, constructing and reusing a single static instance pays off, especially if you are serializing / deserializing often.
