Hi, I've been trying to run a very small UIMA DUCC cluster with 2 slave nodes having 32GB of RAM each. I wrote a custom Collection Reader to read data from an Elasticsearch index and dump it into a new index after certain analysis engine processing. The Analysis Engine is a simple sentiment analysis code. The performance I'm getting is very slow as it is only able to process ~150 documents/minute. To test the performance without the analysis engine, I removed the AE from the pipeline but still I did not get any improvement in the processing speeds. Can you please guide me as to where I might be going wrong or what I can do to improve the processing speeds?
