I am not quite certain if that’s realted but for me it falls into the “performance” category. In two other posts I noticed that Knime becomes quite unstable in the presence of a binary object column. I then noticed it is not exclusive to binary objects as well. Node configuration opens with about 30 sec. delay or sometimes doesn’t open et all. Output preview upon sort throws an error, scrolling to the binary column freezes the preview not even enabling to close it. > [@Binary Object causes Knime instability](https://forum.knime.com/t/binary-object-causes-knime-instability/71416): > > Hi, apologize in advance but this is going to be a rather lengthly bug report. While in a meeting with @DanielBog (wasn’t it you?) and Peter Schramm (I cannot find his nick), I accidentally stumbled across another bug we chucked away as a glitch (explained further below). At least we concluded it was not worth sharing. However, I now face a much more severe issue where Knime becomes totally inresonsive requiring me to force quit it. Previewing data seems also impossible (again continue readin… > [@Sorting causes "Error sorting table: Failed copying file stores to local handler"](https://forum.knime.com/t/sorting-causes-error-sorting-table-failed-copying-file-stores-to-local-handler/71480): > > Hi, it feels like 5.1 has become quite instable. Sorting a table (in preview), which contains about an estiamte of 800 to 1000 MB of images, their binary objects and some text values causes this error. [image] Scrolling to the right where the binary object column resides causes the preview to freeze (moderate CPU but no disc usage). the preview window cannot be close requiring me to force quit Knime.

Maybe this help tracking down the percevied regression here too? Best Mike --- _[View the full topic](https://forum.knime.com/t/ways-to-speed-this-up-10m-rows/70179)._
