Guillemot commented on NIFI-7085:
---------------------------------

Hi.

We facing a similar issue with a limitation of the ConsumeJMS (v 1.11.4) 
performance around 20/30 messages per second. Note that in our case the source 
of messages is an IBM MQ Topic and the messages have a size of 2 kb.
The processor is running on the primary node only, in durable subscription, 
auto_acknowledge and no shared mode.
The primary node is a server with 64 cores and 20Gb of memory.
I sent a mail to us...@nifi.apache.org with more details

 

> Consume JMS is very slow

> ConsumeJMS as primary node consuming only 20 messages per second. 
> If i do all nodes will it read duplicate? 
> If i run multiple thread will it read as duplicate?

> We want to read 2000 messages per sec from Tibco jms.
