MQSeries.net :: View topic - broker 6.1 performance issues regarding esql/flow layout

fde

Hello guys,

Broker 6.1 on AIX
MQ 6 on AIX
Proxyservlet on Tomcat 6

After switching my broker to SSL and approaching massive performance issues I looked for possibilities to optimize.

Regarding the SSL issue I already tested an external httplistener which handles the SSL/HTTP work. Using an external httplistener the Dataflowengine process allocates ~98% of cpu capacity, since much more requests per second can be processed.

After finishing the stresstest, the cpu allocation is still at 98% for Dataflowengine, even hours after the test finished and no further requests were processed.

Further, I thought about optimizing my flow:

Two or more esql compute nodes in a row: Can I achieve better
performance by coding all ESQL operations in one compute node instead of three different nodes after each other?

Currently the flow consists of a http request part and a http reply part in one flow dokument. In between is a MQOutput- and a MQInputNode connection an EIS.
The two parts dont share any scope, so no coding would be neccessary to split the flow.
Would it be better to make two seperate flows instead?
