Hi all, I am writing because I noticed that our pipelines got considerably slower after updating to UIMA3. The cause of the slowdown seems to be the fact that the method getJCasRegisteredType located in TypeSystemImpl uses a synchronised block. We haven't noticed it before but when I was running a pipeline in a large machine (48 cores with 80 worker threads) many of the threads were blocked in this specific method.
I just wanted to point that this is a big problem for us and I am not sure if you are aware or if there is some workaround. I am at this point considering packaging our own version of UIMA without the synchronised block since our types are not dynamic and should be loaded when the pipeline starts so it is unlikely that we need the synchronised access to the type registry.
