------------------------------------

             Summary: State transfer takes more than 10 minutes with only 10K entries.
                 Key: ISPN-1838
                 URL: https://issues.jboss.org/browse/ISPN-1838
             Project: Infinispan
          Issue Type: Bug
          Components: State transfer
    Affects Versions: 5.1.1.CR1
            Reporter: Michal Linhard
            Assignee: Manik Surtani


This could be categorized as a performance problem.

It happened in resilience test run: http://hudson.qa.jboss.com/hudson/view/EDG6/view/EDG-REPORTS-RESILIENCE/job/edg-60-failover-dist-basic/23
originally to verify ISPN-1826
It was run with infinispan special build from Galder's branch (https://github.com/galderz/infinispan/tree/t_1826_5)
http://hudson.qa.jboss.com/hudson/view/EDG6/view/EDG-QE/job/edg-60-build-infinispan-from-source/45/

test starts 4 nodes, kills node2, starts node2 and sees what happens
trace logging on server side was on. there were two runs

200 clients, 10K entries
http://hudson.qa.jboss.com/hudson/view/EDG6/view/EDG-REPORTS-RESILIENCE/job/edg-60-failover-dist-basic/23

20 clients, 1K entries
http://hudson.qa.jboss.com/hudson/view/EDG6/view/EDG-REPORTS-RESILIENCE/job/edg-60-failover-dist-basic/24

in run 24 everyting looks nice:

in run 23 the state transfer takes forever (more than 10 min)


these important views are installed on coordinator (node03):

viewId=8 is the one that takes 10 min to prepare and after that the prepare fails:

viewId=10 is a retry and that succeeds quite quickly but the test is already ending about that time.

It might be worth looking at the tracelogs since they're already there...

10K entries and 200 clients isn't such a big load ...
