@benhunter you should check if you have [enough memory assigned to knime](https://www.knime.com/blog/optimizing-knime-workflows-for-performance). Depending on three size of your tasks half or 2/3 of your system memory might do.

Then you could try and do a restart with the -clean option once:

> Can you add “-clean” as first line in your knime.ini, then restart KNIME and try again? Afterwards, please remove -clean again, as it will slow down the startup otherwise. Cheers, Roland

Then if the software is new you could try and see if an [agressiv virus scanner](https://forum.knime.com/t/knime-takes-long-to-load/12669/4) might hinder the start.
