Summary: QPID 0.32 throughput drop sharply with HA module
Key: QPID-6676
URL: https://issues.apache.org/jira/browse/QPID-6676
Project: Qpid
Issue Type: Bug
Components: C++ Broker, C++ Clustering
Affects Versions: qpid-cpp-0.34, 0.32
Environment: CentOS6.5 X86_64
Reporter: 李翰林
Assignee: Alan Conway
I build QPID 0.32 C++ broker with HA module on CentOS6.5 and run a cluster of 2
nodes with --ha-replicate=all, Then send messages using QPID Messaging API
continuously with protocol AMQP0-10 and I meet a strange problem,If I purge all
of messages in a queue and continue to send messages,The throughput drop
sharply. And the same problem seen on QPID 0.34
Steps to reproduce:
1:
qpid-config add exchange direct testHA.exchange
qpid-config add queue testHA.queue --max-queue-size 1048576000
qpid-config bind testHA.exchange testHA.queue testHA.binding
2:
Run "qpid-queue-stats -f testHA.queue" on a console
3:
Send 100000 messages to testHA.exchange with routingkey testHA.binding
4:
Purge queue use the QPID manager tool (qpid-tool)
5:
Repeat step 3
get the output from step 2:
