[jira] [Commented] (BEAM-2516) User reports 4 minutes to process 1 million line CSV in DirectRunner

    [ https://issues.apache.org/jira/browse/BEAM-2516?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16063511#comment-16063511 ] 

Thomas Groh commented on BEAM-2516:
-----------------------------------

Worth investigating. We do expect things to take notably longer than, for example, a tuned unix utility, but this seems a bit over the top

> I don't know what the expectation are here, so I wasn't ready to say this is WAI. Low priority since it isn't what the runner is for anyhow, but this seems like the scale of data that should be snappy. Worth investigating, or maybe you can quickly indicate why it is expected?
