@snehasish  thanks!

The improvement in startup performance we observed for iOS apps (MachO) are, 
- socialApp1: for cold starts, we reduced 80ms (3%) of the entire app startup 
time (time to network content) on average; 270ms (6%) reduction p95. From 
another perspective, we reduced 5% of the total major page faults for the 
entire app startup phase.
- socialApp2:  for cold starts, we reduced 54ms from app startup on average, 
which is around 12% of the app's premain startup time.
