XML Row Combine and Write very slow after upgrade to 3.6

Dear Forum,

after the upgrade to 3.6 failed completely, I reinstalled KNIME in a minimal version that is completely suitable for me (Standard + Palladian + Selenium). All workflows are working fine and in normal speed, in batch mode or in the UI, except from the last node in each workflow, the xml row combine and write, it tooks an incredible long time to finish.

I was facing the same problem when I upgrade from 3.3 to 3.5 and after unsuccessfully searching for a long time which extension could solve the issue I installed ALL Extensions and the problem was gone.

Is there any experience with that issue, which missing extension could cause the problem while combining and writing XML or are there other cross dependencies with other problems in 3.6 (e.g. the aries.blueprint handler or the failing check integrity of configuration area)?

Thanks a lot for your help, I’m a little bit desperate


Hi @Nordli,

first of all sorry for the late response. We are not aware of any current performance issues related to XML processing. Is it possible for you to provide a workflow and the necessary steps to reproduce this behavior?
