Are you unmarshaling to interface{}? Have you tried commenting out the easyjson json.Un/Marshaler implementations? By default they wrap the easyjson code and add reflection overhead.

I had the same results when testing with a project that is already using easyjson, but after commenting out easyjson's json.Un/Marshaler impls I am seeing much improved performance using goccy/go-json.

Indeed. Thanks for the hint! While the allocations are still 2.5x, not by accident calling into easyjson makes goccy/go-json perform faster than easyjson with generated code by ~10%. That is some impressive result.

Thank you for your report. It's an interesting result. If you have code that can be reproduced, I will try to optimize it to be faster than easyjson.
