How to reduce the size of saved ARIMA model?

[钟雨]

Dear all,

I am trying to save my ARIMA model to disk, but the model seems too large for me. Sometimes 100KB and sometimes few MB, sometimes even 10MB. Is there any way to reduce the model size? I supposed there are a lots of unnecessary fields being serialized.

I found an ancient discussion about it.
