You can also discover what is slow, by adding timeline notifications, or log cards (Simple Log app f.i.)  
-Notification is sent at the time the lights turn on → the trigger is delayed  
-Notification is sent at the time the switch is turned on → the lights respond delayed

Also, Homey is not good at sending too many signals at once.  
And, it fires all action cards at random (asynchronized)  
It’s best to add a little delay between every 2 or 3 lights.

However, the flow editor’s smallest settable delay is one second, which is quite absurd.  
When you group your lights, using an [advanced virtual device](https://community.homey.app/t/app-pro-advanced-virtual-device-device-capabilities-app-with-unique-text-status-indicator/68198) (Device Capabilities app) or \< group \> app, devices are commanded synchronised (one after another, not at once), and with the \< group \> app you can add a delay in the milliseconds range if you like, it is added between every light command
