Radim,
We probably need more info, i.e:
- Number of nodes in the cluster
- How are you measuring the requests?
- Some TRACE logs to inspect the request dispatching? including key name space
information
- What is the test that you're running? Where is the code?
… etc :)
If you can even create a unit test that replicates this issue, even better!! We have an
archetype precisely designed to allow you to create Infinsipan multi node test cases:
https://docs.jboss.org/author/display/ISPN/Infinispan+Maven+Archetypes#In...
Otherwise, you have Martin's arquillian Infifnispan integration to help you create a
test too.
Cheers,

Yes, all the test runs get this result. Note that this occurs in
library mode (not tested in client-server) - I should mention it in the first message.
