Speed varies a lot - my fault or?

Which node-red-contrib-modbus version are you using?
5.23.3
What happened?
When I changed my modbus device (heat pump controller) from connecting over WiFi to ethernet the speed of reading Modbus increase a lot (a factor 10-20 I estimate). That worked well for a long time. When I upgraded to version 5.26 the speed fell drastically, so I reverted to version 5.23 and speed was up again. Now, after a few changes to my flow .. not anything really serious and nothing that to me explains the difference, speed is now down to very slow again. What influences the speed of Modbus performance that much? I have removed all uneccesary nodes and removed a writer.
And then 2 hours later it suddenly runs super fast:
Between the two, I tried to install the v8-profiler node to see if it could reveal anything. It did not work and I uninstalled it and now suddenly Modbus runs super fast.
Now and then (every half hour) I get a lot of these:

Not sure why and not sure how to get more logging info / but does not seem to be related.

How can this be reproduced?
Not really sure - sorry
What did you expect to happen?
I would expect reading items would be 10 times as fast.

Hi @hoegge, the speed depends more on modbus-serial and the 3rd libraries. In the client itself should be no drastic change. An example flow to reproduce this would be helpful for us. You can use the node-red-contrib-helper node to create a real test-flow for our CI/CD pipeline testings to support our investigation.
