Project-in/out scaling & latency

What are some of the limitations around project-in/out nodes?
Specifically around the rate they can handle? does the size of message matter?

I have an application where I'm often publishing (project-out node) over 100k message/hour. Today this surged to about 500k/hour and I'm suspect this lead to a latency of 10's to 100's of seconds of latency. [I'll be measuring this implicitly in the near future]. Before today latency has generally been <10 sec, but I have no idea how much lower, I kinda expect 10ms-100ms, but that's speculation.

Also, does a high usage on certain topics potentially impact performance on other topics (which may have much, much lower usage?

Thank you in advance!

I don't recognize the nodes project in and out. Can you tell us the full node names?

It's FlowFuse nodes: GitHub - FlowFuse/nr-project-nodes: A set of Node-RED nodes for inter-project communication within the FlowFuse platform

Thanks, I should have guessed that from the category. I will leave this for those that know what they are talking about to answer.
