---------------------------------

             Summary: It takes a long time for the sendCAS(cas) method to send a cas to the cas processor, when the cas processor is fast, then the sendCAS method is bottleneck.
                 Key: UIMA-4019
                 URL: https://issues.apache.org/jira/browse/UIMA-4019
             Project: UIMA
          Issue Type: Question
          Components: Async Scaleout
            Reporter: xia yongmin


I have a CollectionReader, a Cas Processor and a Cas Consumer, it takes 1ms for CollectionReader to initialize a cas, 5ms for Cas Processor to analyze, and 1ms for Cas Consumer to consume the cas.

it seems that I can deploy 5 instances of cas processor to obtain 5 times speed.

but when i did this, it didn't work like that.

And I found that it took a long time for the sendCAS(cas) method to send a cas from CollectionReader to Cas Processor.

how can I solve this problem?

many thanks.
