[scikit-learn] Speeding up RF regressors

[Ali Zude]

Hi all,
I've 6 RF models and I am using them online to predict 6 different variables (using the same features), models quality (error in test data is good). However, the online prediction is very very slow. 
How can I speed up the prediction?   
   -     Can I import models into C++ code?
   -     Is it useful to upgrade to scikit-learn 0.18? and then use multi-output models?   

   -     Is sklearn-compiledtreesuseful, they are claiming that it will speed the prediction (5x-8x)times?
   
   - I could not use because of array2d error >>PyPi
Thank you for your help 

RegardsAli
