For comparison, here are the logs for the next view's APPLY_STATE commands. They all
take < 100ms from sending to execution on the target:

One difference that might be significant is that in view 8 all three nodes send their
commands at exactly the same time (within only 1ms of each other). In view 10 the commands
are more spread out, there's about 100ms between the first and the last send.
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: Dan Berindei
Attachments: apply_state.log
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/j...
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-...
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/j...
20 clients, 1K entries
http://hudson.qa.jboss.com/hudson/view/EDG6/view/EDG-REPORTS-RESILIENCE/j...
in run 24 everyting looks nice:
http://hudson.qa.jboss.com/hudson/view/EDG6/view/EDG-REPORTS-RESILIENCE/j...
in run 23 the state transfer takes forever (more than 10 min)
these important views are installed on coordinator (node03):

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 ...
