+There are currently a big performance gap between the 2 clients.

 This is due to a rather old implementation of the synchronous client, we are currently working to update the client code.
 Our aim is to achieve a similar data rate with both clients and at least double the data rate while keeping the stability.
 Table below is a test with 1000 calls each reading 10 registers.
