[jira] [Commented] (PLC4X-165) Frame capture. Multiple writing in a single request.

    [ https://issues.apache.org/jira/browse/PLC4X-165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17008811#comment-17008811 ] 

Christofer Dutz commented on PLC4X-165:
---------------------------------------

Hi [~cgalesanco] ... thanks for these recordings ... from a first check it looks as if we don't have to do any unusual splitting of requests ... the packets look exactly as I would have initially generated them. Perhaps the old driver had another bug that was avoided with the splitting ... if this is really true, then I guess we'll be able to write with the same performance we can read, which would be great.
