Thanks again Sean for the advice. Just by changing the pipeline to use the fast dictionary led to quadrupling the processing speed. Any other suggestions on performance tuning would be great!

To increase the speed you could try swapping out use of ctakes-dictionary-lookup with ctakes-dictionary-lookup-fast in the AE. Check ctakes-clinical-pipeline/desc/[ae]/AggregatePlaintextFastUMLSProcessor.xml for an example. As for the CASPool, I don't think that it will make any difference for cTakes.

I've read most of the UIMA documentation and was able to take the BagofCUIGenerator example and modify to read notes from a DB, process using the UMLS AE in the clinical-pipeline using a local DB version of UMLS, and output the CUIs to a DB. However, the problem I'm having is it's extremely slow; ~3.5-4 notes a minute. I was hoping I could get some hints or advice on speeding the process up. I read there's a patch for LVG, but wasn't quite sure how to implement. Also from testing using the CPE GUI, I don't notice any different in processing time by adjusting the CASPool setting. Some advice on the CASPool would be appreciated also.
