API calls on same json periodically cause nodes to hang & slow down massively

This applies in an API only environment where I'm sending json workloads over. The workloads sent are consistently similar, with small changes here and there on certain values, and some rewiring a few select nodes, but it seems like periodically some nodes will re-load causing big delays as if they're reloading something (but just hanging, it may be the recursive calculation doing empty work? I'm not sure).

Is there a way to get visibility on cached nodes & have some way to keep certain things cached and not needing to run again or having something similar to the UI in terms of caching?
