Hi Harsh,
Do you have any performance issues? Without any information, it is hard to help, did you already have a look at: https://docs.mendix.com/howto/monitoring-troubleshooting/detect-and-resolve-performance-issues/ ?
Hope this helps!
At first you can use the MxAssist Performance Bot, maybe it has some good hints. To check performance, you can use your app in chrome and activate performance recording in the inspector (F12). Afterwards you can analyse the result of the recording.
Maybe you have some more information to your problem.
Hope it helps!
