The version of Nifi where I had UI performance issues was 1.11.4 The current version of our nifi instance is 1.15.3
One other disadvantage of having Process Groups with Stopped components is that when a dataflow manager or a developer inadvertently right click and select “start” on the root canvas page, that will start all the components in the child process groups.

I think we may look into a way of disabling components that doesn't impact version control, or else fix performance issues such that disabling is not necessary. Just out of curiosity, what version of NiFi are you on? The reason I ask is that I know there have been some UI performance improvements made in recent versions of NiFi, so I'm wondering if some of this might already have been addressed...

The only reason why I prefer processors to be disabled is to improve the NiFi UI performance by simply disabling stopped processors which I am not using. https://community.cloudera.com/t5/Support-Questions/Nifi-UI-Working-very-Slow-How-to-increase-performance-of-a/td-p/214550 I had issues with Nifi UI performance in the past where the refresh wheel keeps on spinning like for 10 seconds and disabling stopped processors really helped me.

Please exercise caution before opening attachments, clicking links, or following guidance. Hi Deepak, So far, we have been honoring the following policy for what constitutes a change in version control: 1. stopped/started does not count as a "local change" 2. enabled/disabled does count as a change, and that state is captured in the flow snapshot json version saved to registry. One reason for this is that some users want to setup CI/CD to deploy from Registry and automatically start a flow in the target NiFi. If there are components they don't want to start, the disabled state gives them a way to capture that configuration in the flow. Is there a reason you prefer disable over stop in your lower environment? I leave flows stopped in dev environments all the time and have never run into an issue, but of course, everyone's workflow and use case is slightly different, so I'm interested in hearing your perspective on this to see if we need to consider something more flexible.

In most of the cases both the flows in lower and higher environments will be running. Let says dev nifi connects to dev gcp pubsub and prod nifi connects to prod gcp pubsub. However, in some cases, we do want to stop and disable the flow in lower env. When I do that the registry is identifying that local changes are made to the flow which is nothing but all the components are disabled. I don’t want to keep the processors in stopped state on the canvas(registry do not identify for stopping) but want to disable them. Any workaround for registry not to identify local changes when flow is disabled?
