[jira] [Created] (SYSTEMML-1989) Slow performance of external UDF invocation

Matthias Boehm created SYSTEMML-1989:
----------------------------------------

             Summary: Slow performance of external UDF invocation
                 Key: SYSTEMML-1989
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1989
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


Due to repeated class loading and input/output parsing, we currently only reach about 75K/s invocations of external functions, which is very slow compared to >500K for dml-bodied functions.
