KNIME Takes Long to Load?

You might want to check your virus scanner. On certain systems with quite aggressive virus scanners I experienced KNIME to be slow. Since it can contain several 1,000 single files an ‘agressive’ virus scanner might scan all of them every time they are accessed/opened. When we changed the settings KNIME started faster. Of course there is a trade off between security and speed. But modern virus scanners might be able to have a flexible configuration.

But of course the number of AddOns and the overall performance of the machine also play a part. Considering overall performance you might want to have a look at this thread:

Knime 3.6 Crash when dealing with massive data

you could try and increase the assigned memory in the knime.ini configuration file but with only 4 GB there are limits to that (https://www.knime.com/blog/optimizing-knime-workflows-for-performance). On other option is to set the “Memory Policy” of the (sorter) node to “Write tables to disc”. Obviously this increases the load on the hard drive but it might save on RAM.

If you want to have great models I would encourage you to keep the H2O.ai nodes though
