> Project: Apache NiFi
> Issue Type: Bug

>
> When I run ConsumeJMS against a local broker, the performance is great.
> However, if I run against a broker that is running remotely with a 75 ms
> round trip time (i.e., somewhat high latency), then the performance is pretty
> poor, allowing me to receive only about 30-40 msgs/sec (1-2 MB/sec).
> Increasing the number of threads should result in multiple connections to the
> JMS Broker, which would provide better throughput. However, when I increase
> the number of Concurrent Tasks to 10, I see 10 consumers but only a single
> connection being created, so the throughput is no better (in fact it's a bit
> slower due to added lock contention).
