Is it on every workflow? Or just some?
Could be an environmental thing. I've noticed that as more applications use electron, my performance has gone down a little on my computer and I get even small workflows caching on Run etc.
Most common reason is the below though, but only if it's on some workflows, not all.
By default every time you move something in Alteryx, drag a tool in, configure a tool etc, Alteryx will update the metadata running through the workflow. This can be turned off in User Settings (Auto-configure). However if you turn it off, you will have to use the tick on each config (bottom left), or F5 to refresh the metadata and get the columns you need to appear in the next tool.
Reasons that auto configure can slow down a workflow are related to the amount of metadata that needs to be refreshed. Common reasons for lots of metadata are:
- Text Inputs with over a couple hundred rows (probably up to about 700 is fine on most computers these days, but I generally try to keep them under 300).
- Lots of columns. So, if you have 1000 columns, then that's a lot of metadata, the name/Type/Size/Description of every one of those columns.
- Workflows with a 1000 tools...
If not those, maybe just a re-install, but before doing that, check whether anything has changed in your environment first.
