Clemens did further work on the move/drag-n-drop instrument which can now modify the underlying structure of the data model. This enables to drag-n-drop objects from one open document to another. Furthermore he did some code cleanup and created a GUI component for selecting an active instrument.
I got the object storage up and running and did some benchmarks on the performance of sending objects back and forth between the client and server. The benchmark I did was timing the following sequence of tasks:
- marshaling request in python
- transferring request from client to server
- unmarshaling request in java
- fetching requested object from storage
- marshallng object
- transferring back
- unmarshaling object in python
With small objects (with expected average size) and the server running on a local machine this takes between 1 and 2 ms to complete. This is great results and fast enough for the user interface to be really snappy.
