Aswin K, Most often UI slowness is due to lengthy web requests. You should be able to confirm this by inspecting the Network tab of your browser's Dev tools. If this is the case, which calls are slow? What version of NiFi are you using? How is your flow structured? Are all processors in the root Process Group or have you structured your flow hierarchically?
If the web requests aren't taking too long, what browser are you using? If you are running Chrome 92 there was a regression [1] introduced that affects SVG heavy web applications like NiFi. If you're using this browser I would suggest trying another browser like Firefox.
