I did not have the issue locally last time I’ve checked however I was using a single node so I’m not sure this is relevant.
I’ve tried with a CouchBase 3.0.2 cluster (with the same client library) and response time are much better (average < 5ms) and get and getBulk have similar response time hopefully so I think I’ll will upgrade my clusters.
I’ll try to setup a local cluster with 3 nodes and see if I can reproduce the issue with 2.5.1 and I’ll let you know.
