[jira] [Created] (SYSTEMML-2529) Minor perform boost if you replace replaceAll() with replace()

bd2019us created SYSTEMML-2529:
----------------------------------

             Summary: Minor perform boost if you replace replaceAll() with replace()
                 Key: SYSTEMML-2529
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-2529
             Project: SystemML
          Issue Type: Improvement
            Reporter: bd2019us


Since replaceAll() does not use a regex expression, you can use replace() instead and bypass the performance overhead associated with compiling the replaceAll() regex.
