So do you advise copying tokens in suc= h cases ? What procedure is advisable ?

Specifically for your case with 3 nodes=C2=A0+ RF=3D3, it won't make= a difference so leave it as it is.
=C2=A0
Latency increased on tar= get cluster.

Have you tried to run a = trace of the queries which are slow? It will help you identify where the sl= owness is coming from. Cheers!=C2=A0
