Resolution Note:
As stated here - https://docs.unity3d.com/Manual/ProfilerWindow.html#deep-profiling
"Deep Profiling is resource-intensive and uses a lot of memory. As a result, your application runs significantly slower while it is profiling."
This especially visible on slower Android devices, please disable Deep Profiling to fix this.
