The goal is to improve the transfer speed of data passing from ScalaPy to Python. This would make ScalaPy programs which rely heavily on data switching from one to other run much faster.

The current plan for solving this issue is:

• Replace JNA with JNI in CPythonAPI

• Replace JNA with JNI in Platform

These two alone could bring a speedup of an order of magnitude if not more.

• Find and implement optimization like low-level copying of data (if possible) or using proxies for accessing some data

The last one is the most open as there is no guarantee that optimization can and will be found but it is definitely the most interesting and time demanding.
